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 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)

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 fish (FISHES).
Arthropods of the order Scorpiones, of which 1500 to 2000 species have been described. The most common live in tropical or subtropical areas. They are nocturnal and feed principally on insects and other arthropods. They are large arachnids but do not attack man spontaneously. They have a venomous sting. Their medical significance varies considerably and is dependent on their habits and venom potency rather than on their size. At most, the sting is equivalent to that of a hornet but certain species possess a highly toxic venom potentially fatal to humans.

  • Apart from the value of improved self defense or capacity to kill prey, venom helps bottom dwelling fish by killing bacteria that could otherwise invade their skin. (
  • The strength of the venom varies and can affect prey differently. (
  • This allows the snake to bite its prey without even opening its mouth. (
  • Thanks to this venom, the fire-headed animal is able to prey upon young king cobras, kraits and other agile, dangerous snakes without killing itself on the hunt. (
  • The snakes are at extreme risk from their very dangerous prey," Fry told The Washington Post via email, "so they need to immobilize them before they get killed in retaliation. (
  • Where the venom of mambas and cobras relax their prey into paralysis, the fast-acting calliotoxin jams open sodium channels, causing muscles to hyper-contract into what scientists call "spastic" paralysis. (
  • The two most common ways that snakes kill their prey is with venom or by constriction. (
  • Venom can either slow down or kill the prey. (
  • The cobra uses its teeth to inject poison into its prey and can even spit the venom up to 6 feet at the enemy's eye. (
  • Then I learn that there are also mammals that are able to deliver venom to kill prey or to defend themselves - several in fact! (
  • One component of its venom, which needs to be deadly and fast-acting to swiftly kill its fish prey, has an LD 50 of 0.012. (
  • A wide range of animals have evolved a wide range of venoms over time, chemicals that tend to be painful and are often used to disable prey. (
  • Most species are non-venomous and those that have venom use it primarily to kill and subdue prey and as self-defense. (
  • The protein present in snake's venom constitute the largest portion and cause severe damage in prey by inhibiting important enzymes. (
  • However, some species, such as cobras, boomslangs and rattlesnakes have far more venom than they apparently need-in a single reserve of venom, they have the potential to kill thousands of their prey animals and several adult humans. (
  • Why venoms vary so much in their ability to kill or incapacitate potential prey animals has long puzzled scientists, with several competing hypotheses suggested as explanations. (
  • These results make sense from an evolutionary viewpoint as we expect that evolution will have shaped venoms to be more efficient at killing the prey animals they are most often the target of the venom. (
  • This difference may be due to how often a snake encounters its prey in these different environments, with terrestrial species requiring a larger reserve of venom to take advantage of the rarer opportunities to feed. (
  • This venom can either target the red blood cells and vessels, causing the prey to die from internal or external bleeding, or it can cause the blood to coagulate, making it clot throughout the entire body. (
  • This venom works by either paralyzing the prey the causing the respiratory system to shut down or by overloading the nervous system and causing it to collapse. (
  • Two groups of annelids are venomous: the leeches, whose toxins stop blood from clotting, and the bloodworms, which use their venom to overpower their prey. (
  • it takes only 15 milliseconds for the snake to capture its prey. (
  • Of all snakes, this is the only one known to anticipate the reaction of its prey and act accordingly. (
  • unlike other snakes, it has excellent binocular vision, which allows it to strike at prey with great accuracy. (
  • Its vine-like body hides the snake from both predators and prey (even the tongue is bright green! (
  • If their prey can be easily overpowered the snake will crush them using their powerful abdominal muscles but if not they will follow the wounded animal until their venom takes effect. (
  • Small frogs, fish and other palatable prey are attracted by the allure of an apparently easy meal. (
  • Writing in this months edition of the journal Current Biology, Thomas Schlegel and his colleagues from the Universitat Erlangen-Nurnberg used high-speed photography capable of capturing 5000 frames per second to work out how much force the fish was using to knock prey of its perch. (
  • There were two key findings: The larger the prey the more force the fish used. (
  • Rear-fanged snakes (RFS) are a phylogenetically diverse collection of species that feed on a variety of prey and show varying prey capture strategies, from constriction to envenomation. (
  • Specialized three-finger toxins that target select prey taxa have evolved in some RFS venoms, and this prey capture strategy has appeared in multiple RFS species, from Old World Boiga to New World Spilotes and Oxybelis . (
  • Though this same protein superfamily is commonly found in the venoms of elapid (front-fanged) snakes, no elapid 3FTxs appear to show prey-specific toxicity (with the exception of perhaps Micrurus ). (
  • Neofunctionalization of Spilotes sulphureus 3FTx genes has even resulted in the evolution within a single venom of 3FTxs selectively neurotoxic to different prey taxa (mammals or lizards), allowing this non-constricting RFS to take larger mammalian prey. (
  • Rear-fanged snake venoms are therefore of considerable research interest due to the evolutionary novelties they contain, providing insights into the evolution of snake venom proteins and potential predator-prey coevolution in a broader phylogenetic context. (
  • The venom of conoidean snails - or killer snails, as I lovingly refer to them - allows these slow-moving predators to feed on an agile prey by shutting down a fish's normal functions, preventing them from escaping. (
  • Most snake species have skulls with many more joints than their lizard ancestors, making it possible for the snakes to swallow their prey that are much larger than their heads with their highly mobile jaws . (
  • Nonvenomous snakes either swallow prey alive or kill by constriction, by striking, pulling and holding at its prey, and coils on its prey then wrap one or two coils around their prey until their prey will die of asphyxia (lack of breath), which is contrary to myth that the snakes crush or break the bones of their preys, before swallowing it in whole. (
  • Venoms help animals to immobilise or kill prey, or neutralise predators in self-defence. (
  • Around 150,000 animal species have evolved the machinery to produce venom and inject it into prey. (
  • A venomous animal is one that is capable of injecting venom into its prey through a bite. (
  • The snake's venom incapacitates small prey through haemodynamic collapse driven by catastrophic hypotension and procoagulation. (
  • Shrews must eat constantly, and in order to sustain themselves, they savagely attack prey twice their own size, including mice, fish and frogs. (
  • Lethargically, the fish waits for prey to pass by then opens its lower jaw and sucks its victim in. (
  • Not many animals prey on the scorpionfish, its venom deterring most. (
  • They often shelter under ledges during the day, being more active at dusk and during the night when feed on fishes and crustaceans using their non-stinging pectoral fins to shepherd prey into their mouths. (
  • The team also concluded that the snake's deadly venom was developed during an eons-long "arms race" with prey items: Over many generations, these would-be victims grew increasingly immune to the snake's chemical cocktail, so cobra venom evolved to be more and more dangerous as time went by (which is why, despite the fact that the snakes don't eat elephants, their venom is strong enough to kill one). (
  • This deadly snake has no venom, but kills by coiling around its prey and squeezing its powerful muscles to asphyxiate it. (
  • Coral snakes have a pair of short fangs that they use to emit venom with a neurotoxic poison which paralyses their prey, arresting their respiratory system and killing within seconds. (
  • They inject a paralysing venom from their fangs and then secrete a digestive enzyme that turns their prey into a liquid that they can suck up. (
  • Kingsnakes earned their name because they prey on and eat other snakes. (
  • There are more banded non venomous species than banded venomous species, and all snakes venomous and non venomous, are prey. (
  • Their own predators include larger snakes and birds of prey, particularly owls, which hunt them when they're out and about at night. (
  • Young mole snakes feed on small rodents and lizards, but the adults take only warm-blooded prey which they kill by constriction.For shelter, mole snakes often retreat into the burrows of molerats or gerbils. (
  • Or how spiders and snakes are able to capture prey and to defend themselves? (
  • Northern water snakes are active hunters, and they can use both olfactory and visual cues to hunt for prey. (
  • The "tentacled" snake is the only member of the genus Erpeton, and the two tiny "tentacles" of its namesake are a completely unique feature for detecting prey. (
  • When a fish swims by, it wiggles its tail to frighten the prey straight towards its mouth. (
  • It has very potent neurotoxic venom which it uses to prey or when feeling threatened by attack. (
  • Their main prey item is eel but they have also been observed feeding on small fish such as gobies. (
  • Predators have an arsenal of weapons such as venom, claws or razor sharp teeth to take out their prey with ease. (
  • They are an opportunistic apex predator and eat prey like fish, birds, reptiles, mammals and even humans. (
  • Chironex fleckeri live on a diet of prawns and small fish and are themselves prey to turtles. (
  • Many species of snakes have skulls with many more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. (
  • For example, bees and snakes can both inject a unique venom into their prey or victim as a means of attack or defense. (
  • After a snake bites its prey and injects venom, the serine protease will consume all clotting factors in the blood of the prey. (
  • But in some snake species (for instance the Costa Rican Bushmaster), serine proteases has undergone neofunctionalization, which causes them to carry the normal serine proteases in their blood, but also serine proteases in their venom (along with other proteins) adapted for exerting toxic effect in prey. (
  • When the venom is injected, the serine proteases uses up all of the clotting factors in the prey's blood preventing it from coagulating and allowing the prey to bleed to death after a bite or another injury. (
  • Prey and predators will over time develop resistance against the venom, and the venomous animals cannot afford to stop adapting. (
  • One of the snake species that is not venomous, but instead uses constriction as its strategy for prey subduction. (
  • Their prey can, for example, become better at avoiding venomous animals through improved camouflage or faster reflexes. (
  • A new study by University of Michigan biologists suggests that some predatory marine cone snails evolved a highly diverse set of venoms that enables them to capture and paralyze a broad range of prey species. (
  • Venomous fish are species of fish which produce strong mixtures of toxins harmful to humans (called venom) which they deliberately deliver by means of a bite, sting, or stab, resulting in an envenomation. (
  • For toxins used to stun fish in the fishing practices of certain cultures, see Fish toxins . (
  • Coursing within these twin glands is a venom unlike any chemical previously discovered in snakes, as Fry and his colleagues recently reported in the journal Toxins. (
  • Although there is not yet clinical evidence the coral snake holds the secret to new types of toxin-based pain relief within its glands, researchers have successfully turned snail toxins into painkillers. (
  • These roles include opsonization, activating the complement system, and neutralizing toxins (such as snake and scorpion venom) and toxic organisms (such as bacteria and viruses). (
  • By 1958 a search of the Tropics for venomous animal species in order to isolate and synthesize their toxins was prioritized. (
  • As well as haemo- toxins and neurotoxins, the venom contains dermatonecrotic substances, which cause skin-scarring. (
  • They show this in two ways, first in a table that lists the new toxin peptides identified by their analysis and the toxins that are most similar to those found in other venomous organisms, and, second, in the clustering analysis used to compare and group the approximately 7000 toxin sequences in their database across all venomous animals. (
  • The table shows that most newly identified toxins sequenced in this study are more similar to toxins found in unrelated animals, like snakes and spiders, than to toxins from other cnidarians. (
  • The clustering analysis suggests that the diversification of toxins across venomous groups is independent of evolutionary time. (
  • For example, from most creationist viewpoints, toxins are not expected in the original creation, so it is possible that they would be the result of changes in the venomous species after the Fall. (
  • Both venom and poison are considered toxins . (
  • Venom can contain different classes of toxins, which are generally divided into three categories: hemotoxins, cytotoxins, and neurotoxins. (
  • Some venoms are complex mixtures of toxins of differing types. (
  • These lab-grown mini glands produce and secrete active toxins found in snake venom. (
  • Indeed, various analyses showed that the organoids produce the vast majority of venom components, or toxins, made by the snakes. (
  • Now we saw for the first time that this is also the case for the toxins produced by snake venom gland cells," explained Beumer. (
  • These peptides elicit a wide array of physiological effects in other fishes, though any one species examined produced no more than three distinct putative toxins in its venom. (
  • The large number of 3FTx protein sequences available, together with a growing database of RFS venom 3FTxs, make possible predictions concerning structure-function relationships among these toxins and the basis of selective toxicity of specific RFS venom 3FTxs. (
  • Venoms are cocktails made up of between tens and hundreds of different toxins, usually proteins and smaller chains of amino acids similar to proteins called peptides, along with organic molecules, such as hormones, antibiotics and other compounds that are involved in the metabolic functions of living things. (
  • Venom toxins are among the most potent and precision-targeted molecules on Earth," he explains. (
  • From mankind's point of view, this makes venom toxins ideal templates for drug discovery. (
  • Over hundreds of millions of years, the toxins in venoms have been honed to target highly specific components of their prey's vital bodily functions. (
  • Venom is a complex mixture of toxins," says Takacs. (
  • Using Designer Toxins technology, which he co-invented, Takacs fuses natural toxins from different venomous animals into a single molecule. (
  • Imagine fusing pieces of snake, scorpion and sea snail toxins together and ending up with variants that are rooted in nature, yet have new biological properties," says Takacs. (
  • With around 20 million venom toxins in nature left to explore, it looks like we may be seeing more and more drugs inspired by nature's powerful venoms in our bathroom cabinets. (
  • If it is distressed, its set of 13 spines adjacent to venom glands will protrude from its back, and the toxins released are potent enough to kill a human. (
  • From a young age, we are conditioned to avoid these creatures like the plague, but venom and poison are more than just an organic weapon found in nature, and studying toxins can reveal a lot about life and evolution. (
  • Besides palytoxin, not many studies on the biological activity of zoanthid venoms or toxins have been characterized to date. (
  • According to Suput [ 15 ], an assessment of the pharmacological actions of cnidarian venoms and crude extracts is still missing due to the fact that several types of toxins coexist in the same venom. (
  • So what we do as pharmacologist is we collect all of these venomous creatures from all over the world, we gather their toxins and we create toxin libraries, and we screen that out of this massive toxin libraries which one is the best match for a target in the human body because that can be a potential future medication. (
  • So, in the next few minutes just bear with me and I'm going to show you what it takes to go around the world and collect these toxins because actually the least risky of the whole trip is catching the snake. (
  • Dr. Fry considers the Gulf of Carpentaria to be a Serengeti of Sea Snakes with absolutely staggering numbers of snakes, which allowed for obtaining enough venom to be able to isolate and characterise several novel sea snake toxins. (
  • Molecular phylogenetic analysis of full length toxin sequences demonstrated that the sea snake three-finger toxins (3FTx) were unique in not having evolved novel activities or frameworks, with these peptidic toxins all being antagonists upon the nicotinic acetylcholine receptors (Fry et al 2003a). (
  • In order to better understand the evolution of toxins in the sea snakes, a non-venomous snake was chosen as a negative control for the study. (

  • Venom-related transcripts from Bothrops jararaca tissues provide novel molecular insights into the production and evolution of snake venom. (
  • 2015. Expression of venom gene homologs in diverse python tissues suggests a new model for the evolution of snake venom. (
  • The scientists named the unusual venom calliotoxin. (
  • An international collaboration led by scientists from the National University of Ireland, Galway, The University of St Andrews, Trinity College Dublin and the Zoological Society of London has uncovered why the venom of some snakes makes them so much deadlier than others. (
  • Some scientists have looked at bloodworm venom before, but only in a piecemeal way. (
  • The scientists present findings that suggest parents of fish exchange young with other parents to reduce the chances that their entire brood will be predated. (
  • How can learning about the evolution of venom help scientists? (
  • Similarly, sea snakes in the Gulf have tended not to attract the attention of scientists. (
  • As the scientists note in their paper, sea snakes of the Hydrophiinae family have a common ancestor dating back about 6 million years, although it is in the last 3.5 million years that most of the types that now exist evolved. (
  • But only recently have scientists been in possession of the technology necessary to systematically search through venoms for likely drug candidates. (
  • Even more interestingly, separate teams of scientists are endeavouring to find out how we can use specific fish venoms to treat pain, cancer, and other medical conditions. (
  • According to the scientists, the potent molecules making up the venoms might help them to produce medicines. (
  • As the venom works on these receptors, the scientists believe it might act as a sedative. (
  • One of the world's most beautiful and venomous snakes has a venom unlike that of any other snake, research involving University of Queensland scientists has revealed. (
  • Despite being well known for their venomous sting, many cnidarian venoms have never been studied, including from entire clades. (
  • Cnidarian venoms and extracts have shown a broad variety of biological activities including cytotoxic, antibacterial and antitumoral effects. (
  • Science has learned to harness the power of many venoms for human benefit in recent years - snake venom can help with heart attacks and blood clots, for example, while spider venom may stop brain damage from a stroke. (
  • When we see a snake or spider, it's like an alarm bell goes off in our head. (
  • Venom produced by the snake venom organoids could be used for anti-venom production as well as for targeted development of new venom-based drugs. (
  • The report includes extensive analysis on the historic data across the biotechnology and healthcare segment and forecast for the anti-venom market considering all possible factors impacting the growth. (
  • Continuous research and development to provide innovative drugs and treatment for animal or insect sting has boosted the development of the anti-venom market. (
  • High demand for anti-venom Asia Pacific, Middle East & Asia, and Latin America has attracted regional manufacturers for anti-venom development. (
  • The developing global economic conditions create a huge opportunity for the expansion of the anti-venom market. (
  • Based on anti-venom type, anti-venom market is segmented into monovalent and polyvalent anti-venom. (
  • The market for anti-venom is majorly driven by polyvalent segment. (
  • Anti-venom market is further segmented by distribution channel into four main categories i.e. hospitals, clinics, ambulatory surgical centers, and other distribution channels. (
  • Segment hospital holds largest share amongst the four in anti-venom market. (
  • High cost of anti-venom owing to high production cost and lack in availability of essential anti-venom stock worldwide is major concern for growth of anti-venom market. (
  • Thus, considering this efforts have been taken on national and international level to increase production of anti-venom to gap the supply for anti-venom demand. (
  • The anti-venom market is fragmented, with presence of several large industry players. (
  • The striped fang blenny, native to the western Pacific, is one of several venomous blenny species. (
  • New research shows that conotoxin, isolated from cone snail venom, can numb pain. (
  • Cone snail shells are beautiful, but their venom is a potent cocktail used to paralyze passing fish. (
  • Last week I blogged about the unique properties of cone snail venom. (
  • Cone snail venom has given University of Queensland researchers a lead on the possible detection and treatment of some cancers and addictions. (
  • The toxicity of their venom is calculated by its lethal dose.The most venomous snakes are of lowest values. (
  • Still, even in modern medicine, it has been challenging to fully exploit snake venom for drug development purposes and to protect people against its lethal potential. (
  • Snake venom research has focused on front-fanged venomous snakes because of the high incidence of human morbidity and mortality from envenomations and larger venom yields of these species, while venoms from rear-fanged snakes have been largely neglected. (
  • About 12 fatalities yearly from snake envenomations in the U.S. (
  • By using ecological and evolutionary data for available species we may be able to use our approach as a tool to identify other species which may have properties in their venoms that are useful for biomedical purposes, such as drug development. (
  • Its venom is highly neurotoxin. (
  • The venom of this species consists mainly of neurotoxin. (
  • Research has shown its venom is purely a neurotoxin, with no obvious necrotizing components and no cardiotoxins. (
  • In this blog, Mande Holford, Assistant Professor of Chemical Biology at Hunter College in New York, discusses using venomous marine snails as tools for manipulating cell signalling in the nervous system. (
  • The venom of conoidean snails is similar to that of snakes and scorpions. (
  • Many of these poisons also have important applications in modern medicine-e.g., the venom from marine cone snails may help treat epilepsy and even Alzheimer's disease. (
  • A once rare mutation is known to produce snails with counter-clockwise shells, and since these provide a greater challenge to the snakes, the "mirrored" snails may be growing steadily more common. (
  • With the increased interest in research on marine snakes, we conducted a systematic survey of experts to identify twenty key questions that can direct future research. (
  • These questions are framed across a wide array of scientific fields to produce much-needed information relevant to the conservation and management of marine snakes. (
  • Niue is the absolute outer edge of the sea kraits ( Laticauda genus) and as such was the perfect spot to obtain samples for comparison to the true sea snakes, in order to better understand the evolution of these two independently evolved lineages of marine snakes. (
  • You won't need to have any phobia to be afraid of the Black Mamba, the deadliest snake in the world. (
  • In viper venoms, homotoxins dominate. (
  • Unfortunately, Nerodia water snakes of all kinds are often confused with cottonmouths ( Agkistrodon piscivorus ) an aquatic venomous viper. (
  • The "stilleto" snake has also been called a "mole viper" and "burrowing asp. (
