Limbless REPTILES of the suborder Serpentes.
Bites by snakes. Bite by a venomous snake is characterized by stinging pain at the wound puncture. The venom injected at the site of the bite is capable of producing a deleterious effect on the blood or on the nervous system. (Webster's 3d ed; from Dorland, 27th ed, at snake, venomous)
Solutions or mixtures of toxic and nontoxic substances elaborated by snake (Ophidia) salivary glands for the purpose of killing prey or disabling predators and delivered by grooved or hollow fangs. They usually contain enzymes, toxins, and other factors.
The largest family of snakes, comprising five subfamilies: Colubrinae, Natricinae, Homalopsinae, Lycodontinae, and Xenodontinae. They show a great diversity of eating habits, some eating almost anything, others having a specialized diet. They can be oviparous, ovoviviparous, or viviparous. The majority of North American snakes are colubrines. Among the colubrids are king snakes, water moccasins, water snakes, and garter snakes. Some genera are poisonous. (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, pp321-29)
A family of extremely venomous snakes, comprising coral snakes, cobras, mambas, kraits, and sea snakes. They are widely distributed, being found in the southern United States, South America, Africa, southern Asia, Australia, and the Pacific Islands. The elapids include three subfamilies: Elapinae, Hydrophiinae, and Lauticaudinae. Like the viperids, they have venom fangs in the front part of the upper jaw. The mambas of Africa are the most dangerous of all snakes by virtue of their size, speed, and highly toxic venom. (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, p329-33)
Antisera used to counteract poisoning by animal VENOMS, especially SNAKE VENOMS.
A genus of poisonous snakes of the VIPERIDAE family. About 50 species are known and all are found in tropical America and southern South America. Bothrops atrox is the fer-de-lance and B. jararaca is the jararaca. (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, p336)
Venoms from snakes of the subfamily Crotalinae or pit vipers, found mostly in the Americas. They include the rattlesnake, cottonmouth, fer-de-lance, bushmaster, and American copperhead. Their venoms contain nontoxic proteins, cardio-, hemo-, cyto-, and neurotoxins, and many enzymes, especially phospholipases A. Many of the toxins have been characterized.
A family of snakes comprising three subfamilies: Azemiopinae (the mountain viper, the sole member of this subfamily), Viperinae (true vipers), and Crotalinae (pit vipers). They are widespread throughout the world, being found in the United States, Central and South America, Europe, Asia and Africa. Their venoms act on the blood (hemotoxic) as compared to the venom of elapids which act on the nervous system (neurotoxic). (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, pp333-36)
A family of snakes comprising the boas, anacondas, and pythons. They occupy a variety of habitats through the tropics and subtropics and are arboreal, aquatic or fossorial (burrowing). Some are oviparous, others ovoviviparous. Contrary to popular opinion, they do not crush the bones of their victims: their coils exert enough pressure to stop a prey's breathing, thus suffocating it. There are five subfamilies: Boinae, Bolyerinae, Erycinae, Pythoninae, and Tropidophiinae. (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, p315-320)
Venoms from snakes of the family Elapidae, including cobras, kraits, mambas, coral, tiger, and Australian snakes. The venoms contain polypeptide toxins of various kinds, cytolytic, hemolytic, and neurotoxic factors, but fewer enzymes than viper or crotalid venoms. Many of the toxins have been characterized.
A genus of snakes of the family VIPERIDAE, one of the pit vipers, so-called from the pit hollowing out the maxillary bone, opening between the eye and the nostril. They are distinctively American serpents. Most of the 25 recognized species are found in the southwestern United States and northern Mexico. Several species are found as far north as Canada and east of the Mississippi, including southern Appalachia. They are named for the jointed rattle (Greek krotalon) at the tip of their tail. (Goin, Goin, and Zug: Introduction to Herpetology, 3d ed; Moore: Poisonous Snakes of the World, 1980, p335)
Proteins obtained from species of REPTILES.
Venoms from SNAKES of the viperid family. They tend to be less toxic than elapid or hydrophid venoms and act mainly on the vascular system, interfering with coagulation and capillary membrane integrity and are highly cytotoxic. They contain large amounts of several enzymes, other factors, and some toxins.
A genus of venomous snakes of the subfamily Crotalinae. Twelve species of this genus are found in North and Central America and Asia. Agkistrodon contortrix is the copperhead, A. piscivorus, the cottonmouth. The former is named for its russet or orange-brown color, the latter for the white interior of its mouth. (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, p336; Moore, Poisonous Snakes of the World, 1980, p75)
A genus of snakes of the family VIPERIDAE. About 30 species are currently recognized, found in southeast Asia and adjacent island chains. The Okinawa habu frequently enters dwellings in search of rats and mice; the Chinese habu is often found in suburban and agricultural areas. They are quite irritable. (Moore: Poisonous Snakes of the World, 1980, p136)
A genus of poisonous snakes of the subfamily Elapinae of the family ELAPIDAE. They comprise the kraits. Twelve species are recognized and all inhabit southeast Asia. They are considered extremely dangerous. (Moore: Poisonous Snakes of the World, 1980, p120)
Venoms from snakes of the genus Naja (family Elapidae). They contain many specific proteins that have cytotoxic, hemolytic, neurotoxic, and other properties. Like other elapid venoms, they are rich in enzymes. They include cobramines and cobralysins.
Toxic substances from microorganisms, plants or animals that interfere with the functions of the nervous system. Most venoms contain neurotoxic substances. Myotoxins are included in this concept.
Phospholipases that hydrolyze the acyl group attached to the 2-position of PHOSPHOGLYCERIDES.
Cold-blooded, air-breathing VERTEBRATES belonging to the class Reptilia, usually covered with external scales or bony plates.
A proteolytic enzyme obtained from the venom of fer-de-lance (Bothrops atrox). It is used as a plasma clotting agent for fibrinogen and for the detection of fibrinogen degradation products. The presence of heparin does not interfere with the clotting test. Hemocoagulase is a mixture containing batroxobin and factor X activator. EC 3.4.21.-.
Proteases which use a metal, normally ZINC, in the catalytic mechanism. This group of enzymes is inactivated by metal CHELATORS.
An enzyme that catalyzes the oxidative deamination of L-amino acids to KETO ACIDS with the generation of AMMONIA and HYDROGEN PEROXIDE. L-amino acid oxidase is widely distributed in and is thought to contribute to the toxicity of SNAKE VENOMS.
A family of polypeptides purified from snake venoms, which contain the arginine-glycine-aspartic acid (RGD) sequence. The RGD tripeptide binds to integrin receptors and thus competitively inhibits normal integrin-ligand interactions. Disintegrins thus block adhesive functions and act as platelet aggregation inhibitors.
Toxins, contained in cobra (Naja) venom that block cholinergic receptors; two specific proteins have been described, the small (short, Type I) and the large (long, Type II) which also exist in other Elapid venoms.
The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.

Phospholipases that hydrolyze one of the acyl groups of phosphoglycerides or glycerophosphatidates.
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Compounds that inhibit or block the activity of a PHOSPHOLIPASE A2 enzyme.
A genus of snakes of the family VIPERIDAE. It is distributed in West Pakistan, most of India, Burma, Ceylon, Thailand, southeast China, Taiwan, and a few islands of Indonesia. It hisses loudly when disturbed and strikes with great force and speed. Very prolific, it gives birth to 20-60 young. This viper is the leading cause of snakebite in India and Burma. (Moore: Poisonous Snakes of the World, 1980, p127)
A specific complex of toxic proteins from the venom of Crotalus durissus terrificus (South American rattlesnake). It can be separated into a phospholipase A and crotapotin fragment; the latter consists of three different amino acid chains, potentiates the enzyme, and is specifically neurotoxic.
Instinctual behavior pattern in which food is obtained by killing and consuming other species.
A class of enzymes that catalyze the hydrolysis of phosphoglycerides or glycerophosphatidates. EC 3.1.-.

A 54 kDa cysteine protease purified from the crude extract of Neodiplostomum seoulense adult worms. (1/507)

As a preliminary study for the explanation of pathobiology of Neodiplostomum seoulense infection, a 54 kDa protease was purified from the crude extract of adult worms by sequential chromatographic methods. The crude extract was subjected to DEAE-Sepharose Fast Flow column, and protein was eluted using 25 mM Tris-HCl (pH 7.4) containing 0.05, 0.1, 0.2 and 0.4 M NaCl in stepwise elution. The 0.2 M NaCl fraction was further purified by Q-Sepharose chromatography and protein was eluted using 20 mM sodium acetate (pH 6.4) containing 0.05, 0.1, 0.2 and 0.3 M NaCl, respectively. The 0.1M NaCl fraction showed a single protein band on SDS-PAGE carried out on a 7.5-15% gradient gel. The proteolytic activities of the purified enzyme were specifically inhibited by L-trans-epoxy-succinylleucylamide (4-guanidino) butane (E-64) and iodoacetic acid. The enzyme, cysteine protease, showed the maximum proteolytic activity at pH 6.0 in 0.1 M buffer, and degraded extracellular matrix proteins such as collagen and fibronectin with different activities. It is suggested that the cysteine protease may play a role in the nutrient uptake of N. seoulense from the host intestine.  (+info)

Structural and phylogenetic characterization of human SLURP-1, the first secreted mammalian member of the Ly-6/uPAR protein superfamily. (2/507)

Members of the Ly-6/uPAR protein family share one or several repeat units of the Ly-6/uPAR domain that is defined by a distinct disulfide bonding pattern between 8 or 10 cysteine residues. The Ly-6/uPAR protein family can be divided into two subfamilies. One comprises GPI-anchored glycoprotein receptors with 10 cysteine residues. The other subfamily includes the secreted single-domain snake and frog cytotoxins, and differs significantly in that its members generally possess only eight cysteines and no GPI-anchoring signal sequence. We report the purification and structural characterization of human SLURP-1 (secreted mammalian Ly-6/uPAR related protein 1) from blood and urine peptide libraries. SLURP-1 is encoded by the ARS (component B)-81/s locus, and appears to be the first mammalian member of the Ly-6/uPAR family lacking a GPI-anchoring signal sequence. A phylogenetic analysis based on the SLURP-1 primary protein structure revealed a closer relationship to the subfamily of cytotoxins. Since the SLURP-1 gene maps to the same chromosomal region as several members of the Ly-6/uPAR subfamily of glycoprotein receptors, it is suggested that both biologically distinct subfamilies might have co-evolved from local chromosomal duplication events.  (+info)

Immune response in the garter snake (Thamnophis ordinoides). (3/507)

Garter snakes (Thamnophis ordinoides) were immunized with hen egg albumin, human gamma-globulin and Keyhole limpet haemocyanin in Freund's adjuvant. Antibody was consistently detected by radioimmunoelectrophoresis and in three different gamma- and beta-globulin precipitin lines called IgM (approximately or equal to 20S), Ig-1 (approximately or equal to 9S) and Ig-2 (approximately or equal to 8-5S). Early antibody (day 31 after immunization) was frequently Ig-M whereas Ig-2 and especially Ig-1 were detectable for the longest duration (992 days). After immunization with antigen in Freund's adjuvant, Ig-1 serum concentration showed the greatest increase, from almost undetectable levels to the most prominent immunoglobulin in immune serum.  (+info)

Comparative morphology of the cloacal scent gland in snakes (Serpentes: Reptilia). (4/507)

The histology of the cloacal scent gland, or anal gland, was examined from a diverse group of 50 snakes. Extensive interspecific morphological variation was observed in the general structure of the gland and the glandular epithelium. Morphological variants were quantitatively scored from eight features: lobate nature of the gland; septa in the glandular epithelium; glandular epithelium having a rough or irregular outer surface; glandular epithelium having a rough or irregular inner surface; thickness of the glandular epithelium; PAS reactivity in the glandular epithelium; Periodic Acid-Schiff reactivity in the secretory product; and relative size of the cloacal scent gland. The distribution of the encoded morphological variation was compared to an established phylogeny for snakes and used as the basis for a cluster analysis. In both cases there was no apparent relationship between phylogeny and the morphological variation of the cloacal scent gland.  (+info)

Developmental evolution: this side of paradise. (5/507)

It has long been appreciated that the evolution of snakes involved the loss of limbs and axis elongation, but their developmental basis has been obscure. It has now been shown that alterations in the deployment of Hox genes and an early block in the formation of hindlimb primordia underpin these modifications.  (+info)

Evolution of the ventricles. (6/507)

We studied the evolution of ventricles by macroscopic examination of the hearts of marine cartilaginous and bony fish, and by angiocardiography and gross examination of the hearts of air-breathing freshwater fish, frogs, turtles, snakes, and crocodiles. A right-sided, thin-walled ventricular lumen is seen in the fish, frog, turtle, and snake. In fish, there is external symmetry of the ventricle, internal asymmetry, and a thick-walled left ventricle with a small inlet chamber. In animals such as frogs, turtles, and snakes, the left ventricle exists as a small-cavitied contractile sponge. The high pressure generated by this spongy left ventricle, the direction of the jet, the ventriculoarterial orientation, and the bulbar spiral valve in the frog help to separate the systemic and pulmonary circulations. In the crocodile, the right aorta is connected to the left ventricle, and there is a complete interventricular septum and an improved left ventricular lumen when compared with turtles and snakes. The heart is housed in a rigid pericardial cavity in the shark, possibly to protect it from changing underwater pressure. The pericardial cavity in various species permits movements of the heart-which vary depending on the ventriculoarterial orientation and need for the ventricle to generate torque or spin on the ejected blood- that favor run-off into the appropriate arteries and their branches. In the lower species, it is not clear whether the spongy myocardium contributes to myocardial oxygenation. In human beings, spongy myocardium constitutes a rare form of congenital heart disease.  (+info)

Chemosensitive conductance and inositol 1,4,5-trisphosphate-induced conductance in snake vomeronasal receptor neurons. (7/507)

Snake vomeronasal receptor neurons in slice preparations were studied using the patch-clamp technique in the conventional and nystatin-perforated whole-cell configurations. The mean resting potential was approximately -70 mV; the average input resistance was 3 GOmega. Neurons required current injection of only 1-10 pA to display a variety of spiking patterns. Intracellular dialysis of 100 microM inositol 1,4,5-trisphosphate (IP(3)) evoked an inward current in 38% of neurons, with an average peak amplitude of 16.4 +/- 2.8 pA at a holding potential of -70mV. Application of 100 microM 3-deoxy-3-fluoro-D-myo-inositol 1,4,5-trisphosphate (F-IP(3)), a derivative of IP(3), also evoked an inward current in 4/8 (50%) neurons (32.6 +/- 58 pA at -70 mV, n = 4). The reversal potentials of the induced components were estimated to be -14 +/- 5 mV for IP(3) and -17 +/- 3 mV for F-IP(3). Bathing the neurons in 10 microM ruthenium red solution greatly reduced the IP(3)-evoked inward current to 1.6 +/- 1.1 pA at -70 mV (n = 6). With Cs(+)-containing internal solution, neither the Ca(2+)-ATPase inhibitor thapsigargin (1-50 microM) nor the Ca(2+)-ionophore ionomycin (10 microM) evoked a significant current response, suggesting that IP(3) can elicit current response in the neurons without mediation by intracellular Ca(2+) stores. Intracellular application of 1 mM cAMP evoked no detectable current response. Extracellular application of chemoattractant for snakes evoked a very large inward current. The reversal potential of the chemoattractant-induced current was similar to that of the IP(3)-induced current. The present results suggest that IP(3) may act as a second messenger in the transduction of chemoattractants in the garter snake vomeronasal organ.  (+info)

A fossil snake with limbs. (8/507)

A 95-million-year-old fossil snake from the Middle East documents the most extreme hindlimb development of any known member of that group, as it preserves the tibia, fibula, tarsals, metatarsals, and phalanges. It is more complete than Pachyrhachis, a second fossil snake with hindlimbs that was recently portrayed to be basal to all other snakes. Phylogenetic analysis of the relationships of the new taxon, as well as reanalysis of Pachyrhachis, shows both to be related to macrostomatans, a group that includes relatively advanced snakes such as pythons, boas, and colubroids to the exclusion of more primitive snakes such as blindsnakes and pipesnakes.  (+info)

Wide ranging from dry rocky areas, woodlands, to wet marshes and grasslands. Tiger snakes occur in most habitats in Tasmania. They become inactive over winter, retreating into rodent burrows, hollow logs and tree stumps. Groups of as many as 26 juvenile snakes have been found overwintering in the same place. Generally, tiger snakes do not stay in the same place for more than 15 days, males being especially prone to wandering.. Tiger snakes feed mainly on mammals and birds under 300 g in weight. Tiger snakes habitually raid birds nests and have been found climbing trees to a height of 8 m. A good indicator of the presence of a Tiger snake is the alarm calls of small birds such as honeyeaters and thornbills. They also eat other vertebrates including lizards, smaller snakes, frogs and occasionally fish. Juvenile tiger snakes will use constriction to subdue struggling skinks, a principal food of smaller snakes. Adult snakes are also known to use constriction on larger prey as well. Tiger snakes are ...

Definition of tiger snake in the Financial Dictionary - by Free online English dictionary and encyclopedia. What is tiger snake? Meaning of tiger snake as a finance term. What does tiger snake mean in finance?
Diadophis punctatus, also called the ring-necked snake, is a species of snake. Ring-necked snakes live in eastern and central North America.[4] There are many colors and patterns of ring-necked snake. It is called the ring-necked snake because it has a stripe around its neck that looks like a ring. Ring-necked snakes live in the United States, central Mexico, and southeastern Canada. Ring-necked snakes are nocturnal, which means that they are awake at night. Ring-necked snakes are a little venomous, but they do not hurt people. This is because they are small and do not bite people much. When ring-necked snakes are scared, they curl up their tails. Scientists think that there are many ring-necked snakes. Scientists do not know exactly how many ring-necked snakes there are. This is because scientists have not studied ring-necked snakes very much. Ring-necked snakes are the only species of snake in their genus. There are 14 subspecies of ring-necked snake. ...

Among snake displayers - those who perform at roadside attractions or conduct other demonstrations, often with audience participation - expertise varies. Not all states regulate the industry. Many snake displayers, however, have been working with snakes for decades, and some are herpetologists [sources: MacGuill, Schudel, Klinkenberg].. Professionals aim to get the job done without anyone, including the snake, getting hurt. This means using tools whenever possible [source: Hunter]. Extension tools are standard. Snake hooks or tongs can keep a venomous snake out of strike range while moving or displaying it. Veterinarians often secure a snakes head in a soft, clear tube or the entire snake under a mesh panel for exams or treatment [sources: Hunter, Snake Getters]. Zookeepers use feeding tongs to deliver prey [source: The Cincinnati Zoo and Botanical Garden].. Milking, however, invariably requires free-handling: holding a snake with the hands, not tools. The milker grabs the back of a snakes ...
Most venomous snakes in the United States belong to the family of snakes sometimes referred to as pit vipers. These snakes, which belong to the Family Crotalinae, include rattlesnakes, copperheads, and cottonmouths (water moccasins). All pit vipers in Arizona are rattlesnakes. These snakes are most easily identified by the presence of a rattle on their tail and a triangular shaped head. However, some young snakes may not have developed a rattle yet but still possess venom. When in doubt, avoid contact!. Aside from pit vipers, all other venomous snakes native to the U.S. are coral snakes, which belong to the Elapid family of snakes. Coral snakes found in the Eastern U.S. can be very dangerous to humans, but the Sonoran coral snake, found in Arizona, is not.. Top of ...
Snakes are elongated reptiles without limbs. These serpents have overlapping scales. Snakes are found on every continent except Antarctica, Ireland, Greenland, the islands of New Zealand etc. Additionally they are widespread throughout the Indian and Pacific Oceans. They can be both venomous or non-venomous. Most species are non-venomous and those that have venom use it primarily to kill and subdue prey and as self-defense. Snakes venom contains zootoxins, which are injected into the victim through fang bites or spitting. The gland which produces venom is situated on the either side of the snakes head and are protected by a muscular sheath.. The protein present in snakes venom constitute the largest portion and cause severe damage in prey by inhibiting important enzymes. The toxicity of their venom is calculated by its lethal dose.The most venomous snakes are of lowest values. Most of the worlds poisonous snakes are found in the coastal regions of Australia. Snakes are considered to have ...
The King snake is the KING of snakes in most every domain or region in which they live, and what that means is that they EAT other snakes, and other things that we humans tend to find undesirable, especially high on the undesirable list of King Snake snack foods are rodents such as rats and mice. If eating other snakes - venomous snakes - wasnt enough to endear you to the King snake, then surely eating rats and mice should be.
If you suffer from ophidiophobia, these reports probably gave you a scare. But we have some good news: While venomous snakes are a significant danger in other parts of the world, the United States is almost certainly not going to see a wave of deadly snake attacks, even with a strong El Niño. Yes, sea snakes might be feeding further north this winter, but that does not mean they are going to be out for human prey; likely the only reason this snake came ashore is because it was injured or sick. Furthermore, according to David Steen, a snake expert and researcher at Auburn Universitys Museum of Natural History, there are no known human deaths attributed to the yellow-bellied sea snake, and only about five people per year are killed by venomous snakes of any kind in the United States. By contrast, there were 42 reports of dog-bite fatalities in the United States last year.. Venomous snakes deserve our respect but in many cases the danger they represent is exaggerated, Steen wrote me in an ...
Cobras, vipers, and closely related species use venom to immobilize, injure or kill their prey. The venom is modified saliva, delivered through fangs.[17]:243 The fangs of advanced venomous snakes like viperids and elapids are hollow to inject venom more effectively, while the fangs of rear-fanged snakes such as the boomslang merely have a groove on the posterior edge to channel venom into the wound. Snake venoms are often prey specific-their role in self-defense is secondary.[17]:243. Venom, like all salivary secretions, is a predigestant that initiates the breakdown of food into soluble compounds, facilitating proper digestion. Even nonvenomous snake bites (like any animal bite) will cause tissue damage.[17]:209. Certain birds, mammals, and other snakes (such as kingsnakes) that prey on venomous snakes have developed resistance and even immunity to certain venoms.[17]:243 Venomous snakes include three families of snakes, and do not constitute a formal classification group used in taxonomy. ...
This experiment in the famed garter snake caverns of Manitoba, Canada, was one of the first in a field setting to ever quantify the effects of estrogen as a stimulant of pheromones, scientists said, in research just published in the Journal of Experimental Biology.. This estrogen, they said, is the same exact chemical found in many animal species, ranging from snakes to amphibians, fish, mammals and humans. The research confirms once again the unusually powerful role that estrogen can play in biology, and is also relevant to widespread concern about the environmental impact of compounds that mimic the effect of estrogen, found in some chemicals and pesticides.. In this study, male snakes were implanted with a small capsule that raised their estrogen level to about that of female snakes. After one year of this estrogen supplementation, the male snakes exuded a pheromone that caused other males to swarm to them and form the writhing mating balls that this species of garter snake is known ...
The inborn fear among farmers regarding the toxic venom of snakes plays a key role in killing most snakes, irrespective of whether they are poisonous or nonpoisonous. An interesting fact is that only 150 out of 2000 species of snakes are poisonous.. The coffee forests provide a perfect micro habitat for the proliferation of various snake species. Three important species of venomous snakes, namely the spectacled cobra, Russells viper and common krait are commonly observed inside coffee forests and often come face-to-face with coffee farmers. All the three snake species occupy a variety of habitats, from densely wooded forests to the open wetlands bordering the coffee farms. They are often found under the biomass or on coffee bushes. The fact of the matter is that these three species of snakes are known to use venom only as self-defense.. Various reasons such as expansion of coffee forests into lowlands and wet lands, loss of virgin forests due to new clearings, increasing biotic pressure, both ...
Avoiding detection by a predator is probably the most important weapon in a snakes defensive arsenal. There is an extraordinarly variety of snake coloration patterns. Snakes can be banded, blotched, striped lengthwise, unicolored, or speckled, or a combination of these. These patterns can serve as camouflage when a snake is stationary, where the markings disrupt the form of the snake or match the background. Stripes can help a snake to crawl away quickly because they dont give a predator a reference point to grab onto. Bands can help a snake by disrupting its form when stationary. When a banded snake moves quickly, the bands tend to blend together making the snake look a single color, which makes it difficult for a predator to find a reference point to grab onto ...
Speaking of pigs and snakes… Back in the day here in Mississippi folks let their pigs run loose in the woods. My father has talked about that, and the fact that pigs kept the snake population down, because pigs will kill snakes! I had no idea about this until he and I were having a discussion about how they let the pigs run in the woods. Also, I imagine a cat would be good at catching snakes, but we had a couple of snake dogs when I was growing up. Evidently a dog is either a snake dog or not. One was a mixed breed rat terrier type dog and one was a mixed breed German shepherd type dog. Both dogs could kill a snake in a short amount of time. They instinctively knew just how to do it. On the other hand, our current dogs are more afraid of snakes than I am.. (Not that I am advocating the killing of snakes. I know that they are important parts of our ecosystem and I prefer to live and let live if I possibly can.). ...
This follows from (1) and the setup of the situation. Note that (6) will not be true in the case of snakes that meet a more ordinary end than by complete instant annihilation: those snakes leave behind parts that are no longer informed (they may be parts only in a manner of speaking, but I think nothing in my argument hangs on this). It is to make (6) true that I supposed the snake annihilated instantaneously.. Now, by (4), the claim that the snake is must have been said with respect to some reference frame F1. But it follows from Special Relativity and the geometry of linear snakes that there will be a reference frame F2 relative to which the snake is annihilated gradually from the head to the tail rather than simultaneously. There will thus be a time t2 such that relative to F2 at t2 the snake has been annihilated except for the tailmost one percent. At t2 relative to F2, that tailmost one percent is informed by the form of the snake by (5) and (6). By (2), the snake is alive at t2 relative to ...
In spite of great variation in body size, habitat use, diet, and behavior, the lack of bold, readily apparent distinguishing marks can make identification of southeastern black snakes a daunting task for those inexperienced with snakes. Nonetheless, an informed observer can readily recognize the bright orange belly of the black swamp snake or the namesake ringed neck of the ring-necked snake, and may quickly learn to distinguish between the smooth, glossy sheen of the eastern indigo or black racer and the keeled, somewhat dull look of the black pine and black rat snakes. These snakes may seem nondescript at first glance, though knowledge of these and other more subtle, yet telltale characteristics will assist in the rewarding task of becoming familiar with the black snakes of the southeastern US..

A new study has shown that boosting the estrogen levels of male garter snakes causes them to secrete the same pheromones that females use to attract suitors, and turned the males into just about the sexiest snake in the neighborhood - attracting dozens of other males eager to mate.. This experiment in the famed garter snake caverns of Manitoba, Canada, was one of the first in a field setting to ever quantify the effects of estrogen as a stimulant of pheromones, scientists said, in research just published in the Journal of Experimental Biology.. This estrogen, they said, is the same exact chemical found in many animal species, ranging from snakes to amphibians, fish, mammals and humans. The research confirms once again the unusually powerful role that estrogen can play in biology, and is also relevant to widespread concern about the environmental impact of compounds that mimic the effect of estrogen, found in some chemicals and pesticides.. In this study, male snakes were implanted with a small ...
The show was held on the same site in La Perouse since the early 20th century.[2] The original Snake Man was Professor Frederick Fox,[3] also known as the Snake King,[4] who was proud of the immunity to snake venom that he had developed. However, like other such showmen, he did have his own special antidote. In 1913 Fox travelled to India to sell his antidote. Another local, Herbert See, took over the La Perouse show but he was bitten by a tiger snake and died in hospital.[5] While demonstrating his antidote in Calcutta in 1914 Fox was bitten several times by a krait. He treated himself but overlooked one bite and died after a few hours.[6] George Cann took on the show in the 1920s and the Cann family ran the show thereafter.[7] Snake bites were an ongoing hazard.[8] John Cann was awarded an OAM in 1992 for service to the community, conservation and the environment.[9] The area surrounding the snake pit has been named Cann Park.[10] The last snake man, John Cann, indicated in 2010 that he ...
The mud snake is a bit better known and a bit more commonly encountered, but finding one is still an event, and as little is known about mud snake natural history as about rainbow snakes. Although the two species were once considered to be in different genera (Abastor for erytrogramma), they are clearly sister taxa. The ease of classifying them stops there, however. In order to understand the broader phylogenetic position of Farancia, we need to look at the historical biogeography of North America. Although the dates in question are a matter of some debate, the order of the events I am about to chronicle is fairly solid. The colubroid snake fauna that inhabited the continent 16 million years ago were called the xenodontine snakes. Before the more recent invasion from Asia by and radiation of many of the familiar North American snakes (natricines like garter and watersnakes, colubrines like rat and kingsnakes, elapids such as coral snakes, and vipers), xenodontines had the continent mostly to ...

Neither the author nor are giving medical advice. See a medical professional if you are having problems. Every case is different. The purpose here is to give one case study and show that how it was solved. Your problem, and solution, will likely vary. Foam pads for Anglo handles I got the idea to try this from the review by Chris Timson of his new Dipper baritone Anglo concertina, with raised padded handles higher and more comfortable than the usual design. After seeing how much raised, padded handles helped me, I added this feature to my Dipper order! Before I could do this I had to install new straps that would adjust far enough out for the foam and my small hand (equals a large mans hand if you remove the foam!). I had to repair the wood handle to take a wood screw for a new strap. You can read about that repair separately. ...

Humans perceive snakes as threatening stimuli, resulting in fast emotional and behavioral responses. However, snake species differ in their true level of danger and are highly variable in appearance despite the uniform legless form. Different snakes may evoke fear or disgust in humans, or even both emotions simultaneously. We designed three-step-selection experiments to identify prototypical snake species evoking exclusively fear or disgust. First, two independent groups of respondents evaluated 45 images covering most of the natural variability of snakes and rated responses to either perceived fear (n = 175) or disgust (n = 167). Snakes rated as the most fear-evoking were from the family Viperidae (Crotalinae, Viperinae, and Azemiopinae), while the ones rated as the most disgusting were from the group of blind snakes called Typhlopoidea (Xenotyphlopinae, Typhlopinae, and Anomalepidinae). We then identified the specific traits contributing to the perception of fear (large body size, expressive scales

This snake is an ambush hunter and it assumes a certain pre-strike posture.They anchor themselves to a submerged branch with their tails and prey on small fish as they swim by. These snakes are totally aquatic and nearly helpless on land. The tentacles are soft, and fall to the side when the snake is out of the water.They must surface to breathe. They are venomous.Fangs are small and located in the back of the mouth. ...

Florida has an abundance of wildlife, including a wide variety of reptiles. Snakes, and their cousins the alligators, crocodiles, turtles and lizards, play an interesting and vital role in Floridas complex ecology.. Many people have an uncontrollable fear of snakes. Perhaps because man is an animal who stands upright, he has developed a deep-rooted aversion to all crawling creatures. And, too, snakes long have been use in folklore to symbolize falseness and evil. The ill- starred idea has no doubt colored human feelings regarding snakes.. Whatever the reason for disfavor, they nonetheless occupy a valuable place in the fauna of the region. On the plus side, for example, snakes help keep in check rodents that threaten crops and, not uncommonly, carry diseases that afflict man. Depending on your point of view, Florida is either blessed or cursed with a rich diversity of snakes. Our 44 species of snakes are found in every conceivable habitat, from coastal mangroves and saltmarshes to freshwater ...
Snakes usually do not cause any damage to your home or your garden, but the mere presence of them can be a nuisance to you, your children or your pets. Snakes are good critters to have around because their diet consists of worms, insects and birds that can actually cause more damage to your plants than the snake will. However, if a snake has set up shop under your house or your porch, they will reproduce and then you can have a real problem. When there is more than 100 snakes roaming around your home (and in your home) you are going to want to control it. If you have a snake infestation or have noticed a poisonous snake on your property, you will want to remove it immediately before it becomes a problem or someone gets bitten. Here are a few suggestions you can try: ...
If a health problem is identified in a dangerous snake, which itself depends greatly on the knowledge base of the keeper, how many vets will be keen to see it? he asked.. BVZS president Peter Kettlewell said: It is currently legal for venomous snakes, and other dangerous animals, to be sold in the UK, without the need for a DWA licence. There are also no legal controls when venomous snakes are purchased in EU countries and brought into the UK.. Legally, a DWA licence is only required for animals held by private individuals once they are in the UK. Pet shops are currently excluded from the requirements of the DWA Act and are therefore able to keep dangerous species without a DWA licence. BVZS strongly believes the legislation should be changed to prevent this.. Kettlewell added that, once venomous snakes are in private possession, access to appropriate veterinary care is limited, as there are few vets willing and/or able to treat highly venomous snakes due to the human risks involved in ...
Utiger et al. (2002) examined mtDNA variation in New World and Old World Elaphe and determined that North American rat snakes included in the genus Elaphe formed a monophyletic limeage that is distinct from Old World snakes that also have been regarded as Elaphe. They resurrected the genus Pantherophis for the rat snakes north of Mexico, including the following species: Pantherophis obsoletus (and P. alleghaniensis and P. spiloides, if one recognizes those taxa as species), P. guttatus, P. emoryi, P. vulpinus, P. gloydi, and P. bairdi. Crother et al. (2003) did not follow this taxonomy pending further research, and retained the traditional concept of Elaphe. Burbrink and Lawson (2007) agreed with Utiger et al. (2002) that these species do not belong in Elaphe, but suggested that the genus Pantherophis might belong in Pituophis. We place this species in Pantherophis, following Utiger et al. (2002) pending further information on the relationships of these taxa ...

To ask a question about a snake, dont reply to this post, go to the forum home page and start a new post. Your question will get a lot more exposure. Please give us an idea of where you live, as reptiles can often be identified only by locality!. Please do not place messages about killing a snake, and asking what kind it is you have killed! That is like going onto a message board about dogs and telling about torturing one to death, and asking what kind of breed it was. You will likely get flamed, and likely by the forum owner, depending on his mood that day.. A note about head shape in snakes: Head shape is a totally useless character for identifying a snake, and has nothing to do with whether the serpent is or is not venomous (poisonous). Many harmless snakes, especially when young, have rather large heads. Please describe color, pattern, markings, and habitat where the snake was found. The shape of the head will not help us in any way. Thank you. Please post comments on THIS ARTICLE ONLY! ...
Snakes provide numerous benefits to people and to the environment. In nature, they play an important role in foodwebs by controlling animals that can become pests (e.g. rats and mice). In the laboratory, numerous medications have been developed through investigation of properties of snake venom. Research on the venom produced by one of Floridas snakes (pygmy rattlesnake, Sistrurus miliarius) has enabled the development of a life-saving drug that can be used to thin the blood of human patients experiencing heart attacks.. Most snakes are secretive and rarely bother people. However, there are situations where some snakes can become dangerous. In this document, we present some facts about snakes, describe dangers they may cause, and provide suggestions on how to cope with these dangers.. ...
Al Coritz (ViperKeeper) gave me this amazing 3-piece collapsible Midwest Snake Hook when he stayed at my house for a week. We herped nightly and found a bunch of vipers - of course. This hook is good for any snake over a couple of feet, Id say. Its built to handle the big stuff - like a big python - 3-4 meters, a big king cobra of the same length, or anything else that gets that big. In Thailand there are a few snakes that get over 3 meters - the Keeled Rat Snake (Ptyas carinatus), and only a couple others.. If I had to choose a Best Snake Hook - this would be it. It can be used with all three pieces fitted together, or just 2, or even one - in some limited capacity. The hook is very strong and well made, and they even put a nice blue anodized coating on it. The rubber grips are large and a good idea because they facilitate gripping for handling heavy snakes.. Note: This hook also comes in 2 pieces - each section is about 20″ (51 cm.). ...
Fig. 1A shows the head and tentacles projecting from the face under the scanning electron microscope. The tentacles were covered with scales in all regions including the tips, and higher magnification (Fig. 1B,C) did not reveal scale sensillae (Povel and van der Kooij, 1997) or ampullary type organs - i.e. electroreceptors (Fritzsch and Wahnschaffe, 1983). Similarly, no evidence of such end organs in the epidermis was found in serial plastic sections stained with Toluidine blue or paraffin embedded sections processed for hemtoxylin and eosin or Massons trichrome (not illustrated). As reported by Winokur (Winokur, 1977), the interior of the tentacle was composed largely of collagen fibers interspersed with smooth muscle and contained a number of blood sinuses and vessels. In a 25 cm long newborn snake, the tentacles extended approximately 4 mm from the 1.4 cm length head. In a 66 cm long adult, the tentacles were 6 mm in length extending from the 2.7 cm head. When the snake was waiting to ...

Snakes are the reptiles which are usually found in the grass, rocky outcrops, under or in the logs dense vegetation, in the leaf, in dense of iron & plastic and also along river. They need the sun to heat their body and hide in the afternoon for cooling down.. Some of snake species will be active during the day, night or in hot weather. Most of them are dangerous animals because they are defense character and will attack you if provoked. They usually do not attack if not threatened. For your notice that they are venomous animals.. Million people are bitten by snakes each year. Many of them die, getting amputation or permanently disabled. Actually not all snakes are venomous but we should be careful because of significant bites. A bite of snakes will take you to emergency medical treatment because they can cause bleeding, paralysis, kidney failure, muscle damages, soft tissue destruction or maybe death.. ...
Since the previous answer was so thorough about snake care, Im just going to focus on what kind of snake is best for a beginner and where to get one!. General agreement is that the best beginner snakes in terms of manageable size, temperament, low cost, ease/cost of providing an appropriate habitat, and lack of feeding issues are: corn snake, California king snake, rosy boa, and milk snake. Some people might add ball pythons to this list but personally Im a bit put off by their reputation for being difficult feeders. I know people with balls that are excellent feeders and never turn down a meal... but then again I know of some that regularly go on feeding strikes.. For all of these, captive bred individuals are fairly easy to find at pet stores, local reptile fairs, or local or online breeders. My advice is to avoid large chain pet stores as they often lack staff who are knowledgeable about reptiles and may not take proper care of them. A good locally-owned pet store is a valuable resource as ...
Snakes are reptiles. They are part of the order Squamata. They do not have legs, but they are successful carnivores. There are at least 20 families, about 500 genera and 3,400 species of snake.[2][3] Their long, slender body has some other special features.[4] They have overlapping scales which protect them, and help them move and climb trees. The scales have colours which may be camouflage or warning colours. Many species have skulls with more joints than are in the skulls of their lizard ancestors. This allows the snakes to swallow prey much larger than their heads. In their narrow bodies, snakes paired organs (such as kidneys) appear one in front of the other instead of side by side. Most have only one working lung. Some species have kept a pelvic girdle with a pair of vestigial claws on either side of the cloaca. They have no eyelids or external ears. They can hiss, but otherwise make no vocal sounds. They are very mobile in their own way. Most of them live in the tropics. Few snake species ...
Vertebrate predators have evolved numerous behaviors to efficiently subdue and kill dangerous prey while minimizing their own risk. Many of these tactics involve the use of limbs and associated weapons such as talons, claws and powerful appendicular musculature. As legless predators, snakes evolved other means to immobilize and kill their prey, including venom delivery systems and constriction. Snake constriction is a behavioral pattern in which prey are restrained by two or more points of pressure along the snakes body, typically in the form of one or more encircling loops or coils (Greene and Burghardt, 1978; Greene, 1983; Mehta and Burghardt, 2008). As a key innovation in the adaptive radiation of snakes, constriction behavior enabled snakes to efficiently subdue large prey species not accessible to their lizard ancestors (Greene and Burghardt, 1978; Greene, 1994). Despite its prominence in snake evolution, constriction behavior and physiology are poorly understood and the proximate cause of ...

This is the scary moment a snake slithered across a car windscreen during a storm. The sneaky reptile emerged on the vehicle as it was being driven through Ranong province, southern Thailand, on May 22. Shocked driver Tan Parichad pulled over to remove the creature. She said: I was talking with my husband in the car then the snake just came out of nowhere. It was showing its head on my car windscreen. I was so frightened inside with my family. It wanted to enter the car during the stormy weather. Tan added that she did not know where the snake came from or how it reached the roof of their car. She said: Im not sure where we might have taken the snake. It might have sneaked in while the car was stopped or parked. The couple left the car as they were afraid the snake could somehow enter through a gap. When they were outside, the snake suddenly went to the back of the car to hide from them. After a few moments, it then fell onto the pavement and slithered away from the couple before disappearing into

In the laboratory, courtship and mating stimuli significantly increased the proportion of female garter snakes becoming pregnant, although some noncourted nonmated controls also became pregnant. Females given artificial mating stimuli under anesthetic, without courtship stimuli, were no more likely than either noncourted, nonmated or anesthetized controls to become pregnant. Hormonal changes and yolk synthesis rapidly followed mating in both laboratory and field females; serum estradiol increased more than 10-fold in 2 days and serum calcium, a measure of yolk ...
By Margaret Gillespie, Illustration by Heather Lord. Someone had to do it! One fall day, as the leaves were changing color, I was taking my turn walking the Science Centers coyote, ever watchful for wildlife that she might point out to me or for animals that detect her first and take evasive action. As she began investigating a sunny patch of grass and fallen leaves, a garter snake slowly curved its way forward about two feet and stopped, remaining alert with head up and tongue flickering. Coyote conveniently decided that nothing significant was there and moved on. In contrast, I appreciated this fleeting wildlife sight, for soon New Hampshires snakes would be disappearing from view for the winter phase of their year.. Our most common New England snake, the garter snake, Thamnophis sirtalia, has a variable pattern usually combining a narrow yellow stripe down the back with a wide stripe on each side. Between stripes is a dark checkered pattern. Garter snakes received their name because this ...

The Common Garter Snake has been said to be the best-studied snake in the world. Among other studies, its interaction with the Rough-skinned Newt is perhaps the most interesting. These newts are extremely poisonous, the tetrodotoxin in their body enough to kill anything that tries to eat them (including even large mammals). Some populations of garter snakes have evolved physiological defenses against this toxin and can eat newts freely. Other populations cannot. This is said to be an arms race between predator and prey, the prey evolving defenses and the predator evolving mechanisms of countering them ...
Some people ask this question when they see a snake in the water. Unfortunately, many people assume all snakes in the water are cottonmouths and kill them just in case. Along with sharks and bats, snakes are among the most misunderstood and mistreated animals on earth. Yes, some species of snakes, including the cottonmouth (Agkistrodon piscivorus), also known as the water moccasin, are venomous and therefore a potential danger. However, of the 32 snake species native to Tennessee, only 4 are venomous all others are completely harmless. Among the 28 harmless nonvenomous snakes, water snakes (Nerodia and Regina species) and eastern hognose snakes (Heterodon platirhinos) are often unfortunate victims of mistaken identity thought to be cottonmouths. This brochure was developed to highlight the differences between water snakes, hognose snakes, and cottonmouths with the hope that familiarity with these snakes will prevent further unnecessary killing of snakes. ...

Snakes alive! Otowi Station, Snake Conservation and the Bradbury Science Museum are collaborating for a presentation and demonstration at 1:30 p.m. Wednesday in the breezeway between Otowi Station and the Bradbury Science Museum. Visitors can see all kinds of beautiful snakes, learn the part they play in our environment, and get an exclusive deal on a Snake Sack, which contains a guidebook, a notebook for recording the kinds of snakes they observe, a pencil and a museum-quality replica of a snake. The Bradbury Science Museum will feature videos about snakes from 10 a.m.-5 p.m. and have some special exhibits about snakes. Snakes are often hated and feared. Many are even killed for no clear reason. But there are definitely reasons to keep snakes around your home or garden. They can keep in check pests like rats and mice, which are vectors for such diseases as Hantavirus and the plague. And some species that are harmless to people prey on venomous snakes, reducing the chance of a deadly encounter. A worker
The first two of those features are not found in any other known snake in the family Colubridae in the Western Hemisphere. Colubridae is the largest snake family and includes just over 51 percent of all known living snake species.. Utilizing the vast resources of UTAs Amphibian and Reptile Diversity Research Center for comparative purposes, the researchers made CT scans of dozens of specimens of snakes. The biologists believe that due to some of the specimens physical features, Cenaspis is likely a burrowing snake that feeds on insects and spiders. Campbell believes that Cenaspis is not extinct but has eluded capture due to its burrowing lifestyle and other elusive habits.. This provides evidence of just how secretive some snakes can be, Campbell told National Geographic, which ran a story about the discovery in its Dec, 19, 2018, edition. Combine their elusive habits with restricted ranges and some snakes do not turn up often.. He noted said that because of the snakes unique nature, the ...
Garter snakes, sometimes called garden snakes, are small nonpoisonous snakes that live in your yard. There are different varieties, but the most common have subtle colors. Usually they have dark but soft hues of black or green, with a yellow or red set of stripes running the length of their backs.
Garter snakes in Missouri are typically dark colored and have orange, yellow or white stripes that run lengthwise down the body of the snake. The snake may
The snake itself is one of the oldest and most widespread mythological symbols. Some snakes serve as positive symbols with whom it is possible to identify or to sympathize; in other instances, snakes serve as negative symbols, representing opponents or antagonists of figures or principles with which it is possible to identify. An example of a snake used as a positive symbol is Mucalinda, the king of snakes who shielded the Buddha from the elements as the Buddha sat in meditation. An example of a snake used as a negative symbol is the snake who tempted Adam and Eve in the Garden of Eden, as described in the Book of Genesis. Because of the Biblical portrayal, as well as other roles in popular cultural myths, such as ancient Babylonian and Greek mythology, snakes are typically seen as the negative symbol and thus as villainous characters.

Uthra (25), a resident of Eram Vellasheeril, was found dead by a snake in her room.. The cyber cell found that Suraj, hailing from Adoor Parakkodu, had been in constant contact with some snake takers. Snake takers and some of Soorajs aides are under surveillance.. Sooraj claims that a snake which entered through the open window had bitten Utra. More scientific testing is needed to determine whether this is true. The key is to find out how much the snake can rise from the floor. In this regard, we are seeking the knowledge of zoologists and snakes.. Those who work in this field say they are awakened by a poisonous snake bite. But Uthra did not wake up. Police are hoping to know the cause of the post-mortem. Delay in getting the report is affecting the investigation.. On March 2, Uthra was bitten by a snake at ...

There are more than 25 different venomous snakes in Australia. The mere thought of encountering one makes me do a tiny vomit in my mouth. Almost. I should definitely consider moving to a nice, snake-free country like New Zealand. Throughout Australia, most (most than 75%) snake bites are from brown snakes, but here in Victoria tiger snakes account for around half.. Snake bites are common in our pets, because these creatures are often outside sharing the same space, and our four-legged friends usually cant resist hunting or playing with things that move. Snake bites are usually seen during the warmer part of the year from September through to April, with most cases occurring over summer. The severity of symptoms and how quickly they occur depends on how many times a pet is bitten and where on their body they are bitten.. Unfortunately bites often occur on the face or in the mouth, because this is the body part that pets are usually poking at the snake. Right at this moment we have an adorable ...
Biologist Ron Larche says it will be about a year before they can estimate how many were lost. To try to get an estimate of the number of snakes still using the area, we will have to wait until next spring until we can do a mark recapture study and arrive at an estimate of the number of snakes still using the den, Larche said. We do know from a mark recapture study last year we had 65,000 snakes using the area. The snake dens in Manitobas Interlake are in a protected wildlife management area. The site is a unique feature that has attracted visitors from around the world. Larche says officials are consulting with international snake experts to try to figure out what happened. He says biologists believe the reptiles died of natural causes. ...

Selecting a Snake. Before you acquire your snake, you should do some research on the particular species that you are interested in. Different species have varied husbandry and dietary requirements, physical appearance (such as length), temperaments, and environmental considerations. Some snakes, such as boa constrictors and ball pythons, have gentle and very docile temperaments. Others, such as the reticulated and Burmese pythons, are unpredictable and tend to be aggressive as they mature. Anacondas rarely adapt well to captivity. Some snakes reach very large sizes in captivity: for example, the boa constrictors and pythons can grow up to sixteen feet. It is illegal (and foolish) to house venomous/poisonous snakes unless you are an experienced herpetologist with a license from the DSE to do this. Select a snake that looks healthy and is eating regularly. Never buy a snake that looks sick, even if the price is a bargain. You will end up paying more in veterinary bills.. Housing. Aquariums and ...

Snake Bite Prevention Tips. With warmer temperatures occurring, you need to be careful about encountering snakes outside in different areas of your yard, in parks, or in the woods and fields. Remember to be observant and to teach your children about snake bite prevention. Use common sense and never reach under rocks, bushes, or other areas where you cannot see and where a snake may be living. Most people get bitten on the hands or feet when they inadvertently step on a snake, or reach where they cannot see.. Most of the 27 species and subspecies of snakes found in Maryland are not venomous like the Northern brown snakes, rat snakes and garter snakes. However, there are two types of venomous snakes found in Maryland. They are the eastern copperhead and the timber rattlesnake (not found in Charles County). The eastern copperhead snake is venomous and found in Charles County. Do not attempt to capture or handle it. They will bite if provoked, and the bites are extremely painful. Seek medical ...
TY - JOUR. T1 - The molecular basis of cross-reactivity in the Australian Snake Venom Detection Kit (SVDK). AU - Winkel, K.. AU - Carroll, T.. AU - Williamson, N. A.. AU - Ignjatovic, V.. AU - Fung, K.. AU - Purcell, A. W.. AU - Fry, B. G.. PY - 2007/12/15. Y1 - 2007/12/15. N2 - The Snake Venom Detection Kit (SVDK) is of major medical importance in Australia, yet it has never been rigorously characterised in terms of its sensitivity and specificity, especially when it comes to reports of false-negative and false-positive results. This study investigates reactions and cross-reactions of five venoms the SVDK is directed against and a number of purified toxins. Snakes showing the closest evolutionary relationships demonstrated the lowest level of cross-reactivity between groups. This was, instead, far more evident between snakes that are extraordinarily evolutionary separated. These snakes: Pseudechis australis, Acanthophis antarcticus and Notechis scutatus, in fact displayed more false-positive ...
Snakes as a major reptile group display a variety of morphological characteristics pertaining to their diverse behaviours. Despite abundant analyses of morphological characters, molecular studies using mitochondrial and nuclear genes are limited. As a result, the phylogeny of snakes remains controversial. Previous studies on mitochondrial genomes of snakes have demonstrated duplication of the control region and translocation of trnL to be two notable features of the alethinophidian (all serpents except blindsnakes and threadsnakes) mtDNAs. Our purpose is to further investigate the gene organizations, evolution of the snake mitochondrial genome, and phylogenetic relationships among several major snake families. The mitochondrial genomes were sequenced for four taxa representing four different families, and each had a different gene arrangement. Comparative analyses with other snake mitochondrial genomes allowed us to summarize six types of mitochondrial gene arrangement in snakes. Phylogenetic
The Bushmaster is a nocturnal species but will move around during the daytime. It is an aggressive snake particularly when agitated or startled. Coral Snakes. Coral snakes are small thin snakes of about 60 to 100 centimeters with small heads that are the same size as their body and small round eyes. Their round eyes are one of the features that make them different from most poisonous snakes. Venomous snakes have vertical slits for pupils while non-venomous snakes have round pupils. Coral snakes are however the exception to the rule in that they have round eyes. Coral Snakes are very beautiful with their body being marked with bands of red, black and yellow. There are several other snake species that also have red, black and yellow bands but these species are not venomous (poisonous). In order to distinguish the venomous species of coral snake a small rhyme has arisen, which states Red and yellow, kill a fellow, red and black, venom lack. The meaning of this rhyme being that where a snake has ...
Non-venomous, Nerodia fasciata hunts fish and a wide variety of amphibians, particularly frogs. A nocturnal hunter, N. fasciata spends the day resting in the vegetation along the waters edge or hides deep in rodent burrows along the bank. Many species of Nerodia are suspected of being venomous cottonmouths (Agisktrodon piscivorus) but the behavior of the two snakes is tremendously different. Cottonmouths move much more slowly in the water, often keeping their entire body afloat. When threatened, cottonmouths show off their namesake white lined mouth in a defensive posture. All species of Nerodia are quick, agile swimmers which move rapidly through the water and water snakes never gape open their mouths if threatened. They may instead flatten their bodies in an attempt to look larger.. ...

They are commonly found in rock and debris piles, animal burrows and crevices. They will seek out roads, open sandy areas and rocks to sun themselves during cooler temperatures.. They are more active in spring and summer. But it is important to remember you can encounter rattlesnakes anytime and anywhere. Rattlesnakes prey on mice and other small rodents. They dont lay eggs, but rather give live birth to young snakes about 9 to 12 inches long.. Like other snakes, mammals and birds, rattlesnakes fill an important place in the ecosystem by preying on rodents and keeping their populations in balance. When the rattlesnake is found in a backyard, this ecological role may not seem so apparent or important.. Other snakes such as the gopher snake, red racer and king snake are common on Edwards. Many people kill gopher snakes confusing their tan coloration and indistinct black markings for a rattlesnake.. Gopher snakes, red racers and other snakes often hiss and shake their tails imitating the motion ...
Most dog owners dread the thought of their dog being bitten by a snake. In many areas of the United States, venomous snakes are a real concern.

CORVALLIS, Ore. - A new study has shown that boosting the estrogen levels of male garter snakes causes them to secrete the same pheromones that females use to attract suitors, and turned the males into just about the sexiest snake in the neighborhood - attracting dozens of other males eager to mate. This experiment in the famed garter snake caverns of Manitoba, Canada, was one
In order to elucidate the phylogenetic relationships in European ratsnakes of the genus Elaphe, we analyzed a 597 bp part of the mitochondrial cytochrome b gene of eight West Eurasian and one East Asian species. Lampropeltis served as outgroup. Maximum parsimony and maximum likelihood suggest the existence of four lineages: 1) E. scalaris; 2) the E. longissima species group comprising E. longissima, E. lineata, E. situla, E. hohenackeri, and E. persica; 3) E. quatuorlineata and 4) E. dione as a sister group to 3). Elaphe scalaris is basal and shows no closer affiliation with any other analyzed species. The Middle Eastern E. persica and E. hohenackeri appear basal within the E. longissima group. Elaphe lineata differs by 8% nucleotide substitutions from E. longissima, supporting the hypothesis that both taxa represent distinct species. Elaphe situla is associated with Elaphe longissima and E. lineata. Three analyzed subspecies of E. quatuorlineata are represented by distinct haplotypes. The extent of

Twelve snakes involved in a public outreach program, representing seven different species, were tested weekly for shedding of Salmonella sp. over a period of 10 consecutive weeks. The snakes were housed in close proximity but in separate exhibits. Fresh fecal samples (when available) or cloacal swabs were cultured for Salmonella sp., and subsequent Salmonella isolates were serotyped. As representatives of the feed source, the feces of two mice and the intestines of one rat were cultured weekly. Fecal samples from 11 of the 12 snakes were positive for Salmonella at least ...
Snake venom is a wily beast. Its packed with hundreds of toxins that can attack our blood vessels, muscles and nerves. Thats why snake bites kill some 100,000 people each year. On todays show - dangerous snake bites and the bizarre way we make the only thing that can save you from them: antivenom. (Spoiler alert: it takes snake milkers and stables filled with horses.) Well also look at the groundbreaking research that could eventually revolutionise all this. We speak to Captain Pete Bethune, snake venom researchers Dr. Christina Zdenek, Professor José María Gutiérrez, Dr. Laura Albulescu and snake milker Greivin Corales.
Title: Hypotensive Agents from Snake Venoms. VOLUME: 4 ISSUE: 4. Author(s):Roy Joseph, Susanta Pahari, Wayne C. Hodgson and R. Manjunatha Kini. Affiliation:Department of Biological Sciences, Faculty of Science, National University of Singapore, 14 Science Drive 4, Singapore 117543.. Keywords:bradykinin potentiating peptides, natriuretic peptides, sarafatoxin, endothelin, calciseptine, conotoxins and calcium current, vascular permeability, l-type calcium channel, cardiovascular effects. Abstract: Many snake venoms contain toxins which produce profound cardiovascular effects. The site of action of these toxins includes cardiac muscle, vascular smooth muscle and the capillary vascular bed. Some snake venoms, for example, contain peptides that inhibit angiotensin converting enzyme and potentiate the biological actions of bradykinin. Other snake venoms contain structural and functional equivalents of mammalian natriuretic peptides. Sarafotoxins are short peptide toxins found in the venoms of snakes ...
Snakebite often results in puncture wounds caused by the animals fangs and sometimes, envenomation. Most snakes are non-venomous and kill their prey with constriction, however, venomous snakes often bite their prey as a method of hunting and sometimes as a defence mechanism when they are attacked or disturbed.. First Aid in the case of snake bite. According the the World Health Organization (WHO), the recommended procedure for snake bite first aid is the R.I.G.H.T. method.. Reassure the victim. Keep the victim calm. If the victim panics, their heart rate and blood pressure will increase and make the venom spread faster. It may also lead to anaphylactic shock which could kill the victim faster than the venom. Assure the victim that almost 70% of all snakebites are from non-venomous snakes and of the remaining 30%, only half will actually have injected venom, the rest being Dry Bites. Assure them that they are going to be OK.. Immobilize the affected limb. Do not use compression.. If a bite is ...
Robert Powell, a biology professor and snake expert at Avila University in Kansas City, said the Brahminy blind snake - a small burrowing animal native to southeast Asia commonly known as the flowerpot snake - has long been the only known snake that routinely reproduces without a males contribution.. In the Missouri case, its possible - but unlikely - that momma snake simply stored sperm from her time in the wild. But Michelle Randecker, a naturalist at the center, said eight years is too long. Powell agreed, saying a female snake usually cant store sperm for longer than a year, although there are accounts of successful storage as long as three years.. Long-term storage is unusual. When you run into situations like this, you always wonder, Is that a possibility? he said. If nothing else, its an interesting phenomena. Whether this is long-term storage or parthenogenesis, its cool. Just another sign that nature works in mysterious ways.. AJ Hendershott, outreach and education regional ...
