The common name tuatara comes from Maori words meaning spines on back, in reference to the crest on the backs of males and females. Tuatara have a lizard-like appearance: both groups are elongate with four limbs (most lizards) and both lizards and tuatara are known to shed their tails (caudal autotomy). The groups diverge, however, on the presence or lack of a paired hemipenes, the morphology of the teeth and skull, and other important features. Tuatara are long-lived species, reaching sexual maturity at about 20 years. Two species of tuatara, Sphenodon guntheri and Sphenodon punctatus, are located in New Zealand, and are the only species known to exist ...

Cotylosauria is considered as stem - reptiles. They closely resemble the Labyrinthodont amphibians. It is not easy to distinguish these two groups separately. In the Mesozoic era giant dinosaurs dominated the earth. In the late cretaceous period of Mesozoic era they became extinct In the present day world nearly 5,000 known species of reptiles are living. Reptiles are poikiothennic vertebrates. They are first true land vertebrates. They are the first amniotic group of vertebrate animals. The Present day reptiles are sphenodon, lizards, snakes, turtles and crocodiles. GENERAL CHARACTERS OF REPTILES The Reptiles origin from labyrinthodont Amphibians in the carboniferous period of Paleozoic era. Present day living Reptiles are 5,000 species.

Reptiles have become increasingly common as domestic pets, and with them reptile-associated Salmonella infections in humans. From 1990 to 2000, a total of 339 reptile-associated Salmonella cases were reported in Sweden. In 1996, as part of its efforts to adapt its import regulations to those of the European Union, Sweden no longer required certificates stating that imported animals were free of Salmonella. A subsequent increase was noted in the incidence of reptile-associated cases from 0.15/100,000 in the period 1990-1994 to 0.79/100,000 in 1996 and 1997. After a public education campaign directed toward the general public was begun through the news media, the incidence dropped to 0.46/100,000. Children were the most affected age group among patients (incidence 1.3/100,000). Salmonella enterica serotype Enteritidis was the most frequent serotype (24% of isolates), followed by S. Typhimurium (9% of isolates). Import restrictions and public information campaigns are effective public health measures
Reptile is the common name for one of the main groups of land vertebrates. It is not used so much by biologists, who use more accurate terms. The name reptile comes from Latin and means one who creeps. All living reptile species are cold blooded, have scaly skin, and lay cleidoic eggs.[1][2] They excrete uric acid (instead of urea), and have a cloaca. A cloaca is a shared opening for the anus, urinary tract and reproductive ducts. Reptiles also share an arrangement of the heart and major blood vessels which is different from that of mammals.[3] Many important groups of reptiles are now extinct, for example the mosasaurs. We used to say the dinosaurs were extinct, but they survive in the form of their feathered descendants (birds). Ancient reptiles that do survive include the turtles, the crocodiles and the Tuatara, the lone survivor of its group. The great majority of present-day reptiles are snakes and lizards. The study of living reptiles is called herpetology. ...

There are countless species and varieties of reptiles around the world. Even though there are many differences, reptiles do share a few common traits.For starters, they use lungs to breathe. Lizards might breathe using the same muscles they use to run and crocodiles have a more flexible diaphragm, but overall, reptiles have lungs that are more advanced than amphibians, but not as refined as mammals. Reptiles also have scales made of keratin protein. Scales provide protection from predators, help retain water, and can play a role in courtship and territorial clashes. Reptiles are not the only animals to have scales, but it is a common characteristic among all reptiles.Another characteristic is that theyre all four-legged vertebrates (or descended from four-limbed animals, like snakes). This is another shared trait with other types of animals, which indicates that reptiles are an evolutionary middle ground of sorts between amphibians and mammals. For the most part, female reptiles lay eggs but ...
A very common myth is that reptiles are cold-blooded. In addition to describing a general temperature of reptilian blood, the term also entails the negative connotations of evil and lifelessness. To be sure, in the Biblical story of Adam and Eve, it was a serpent that deceived mankind. However, reptiles are not cold-blooded. On occasion, they are quite the contrary and can even be hot-blooded. This gradation results in reptiles being poikilothermic. Poikilotherms have a body temperature that is variable with environmental conditions. If the ambient temperature is warm or even hot, that leads to a reptile having warm or hot blood. Another physiological term that accurately depicts reptiles is ectothemy. Ectotherms control the uptake of heat from the environment as a way to control internal body temperature. Reptiles are both poikilothermic and ectothemic, but are not cold-blooded. Moreover, some larger reptiles, such as large crocodilians, sea turtles and large monitor lizards approach ...
The results presented here add a critical lineage to the emerging picture of MHC evolution in amniotes, with a genome-level characterization of MHC organization in an evolutionarily divergent reptile, the tuatara. The tuatara MHC region appears to be large with a high repeat content. We found a total of seven class I sequences and 11 class II β sequences, but some appeared to represent pseudogenes. Chromosome 13q appears to contain the core MHC, as clones containing classical class I, class II beta, and class II alpha chain genes map to here, but additional class I genes were located chromosome 4p.. The MHC in tuatara has low gene density compared with other species. We found at most five genes on individual BAC clones, and many clones contained only one or two genes and a high number of repetitive elements. The low density of tuatara MHC genes is a likely reason for challenges in identifying other MHC-associated genes like TAP1, TAP2, TAPBP, or C4 or framework genes like DAXX, BRD2, or TNXB on ...

When we think of reptiles and their parasites, we tend to (or should be!) thinking about how the presence of bloodsucking ectoparasites and the many different types of endoparasites may harm our reptile. While a healthy reptile can sustain a certain number of endo- and ectoparasites, a stressed or already compromised reptile cannot. Since captivity is, in and of itself, stressful, experienced herpers learn that it is better to deal with the issue right from the start, rather than wait for a problem to develop and to spread throughout all their other enclosures and reptiles.. What most herpers - and other pet owners - fail to realize is that humans may become infected with diseases borne by the ectoparasites, as well as become infected with organisms that pass through the reptiles digestive tract (nicely known as the fecal-oral route). What follows are abstracts and other information on some of the tickborne and other zoonoses from reptile hosts.. Seasonal activity and host associations of ...
During 1994-1995, health departments in 13 states reported to CDC persons infected with unusual Salmonella serotypes in which the patients had direct or indirect contact with reptiles (i.e., lizards, snakes, or turtles). In many of those cases, the same serotype of Salmonella was isolated from patients and from reptiles with which they had had contact or a common contact. For some cases, infection resulted in invasive illness, such as sepsis and meningitis. This report summarizes clinical and epidemiologic information for six of these cases. Connecticut. During January 1995, a 40-year-old man was hospitalized because of an acute illness characterized by constipation, lower back pain, chills, and fever.

Reptiles have dry scaly skin rather than hair or feathers. But they dont need moisturizer! Their special covering actually helps them hold in moisture and lets them live in dry places.. Reptile scales are connected in a sheet, which is the outermost layer of skin. Every so often, this layer of skin is shed and replaced. In some reptiles the skin flakes off in chunks. In snakes, the skin is usually shed in one piece. You may not think of turtle and tortoise shells as being scaly, but they are! Theyre shells are complex structures made up of bones and scales that develop from the outer layer of skin. Its natural body armor!. Heating Up and Cooling Down. Reptiles, like amphibians, are ectotherms ( cold-blooded). This means that they cant produce sufficient internal heat to maintain a constant body temperature. Instead, reptiles are responsible for regulating their own body temperature. When its cold outside and they need to warm up, they often bask in the sun to raise their body ...
Diseases of reptiles eyes are frequently seen in veterinary practice. The causes of these lesions are often identical to those responsible for inducing ophthalmic disease in mammals and birds. Although the approach to treatment is similar to that in mammals, anatomic differences in the reptile eye cause special conditions to reptiles. Because ciliary muscles of reptiles are composed of striated muscle rather than smooth muscle fibers, conventional mydriatic agents (parasympatholytics) such as tropicamide and atropine are ineffective in producing pupillary dilation. The second difference is that in those reptiles lacking movable eyelids, the corneas are covered by a clear protective epidermally derived structure called spectacle. This structure appears impervious to topical medications, thus making treatment of the globe difficult. The spectacle is periodically replaced during molting cycles (ecdysis).. Congenital ocular malformations (especially microphthalmos) occur with some frequency in ...
However, while reptiles are often easier to maintain and require less attention than a dog or cat, their convenience comes at a price. Reptiles usually require specialized food and specific living conditions. Quite often, potential owners must have their cages custom built and have to monitor things such as lighting and heat within the cage at all times.. Reptiles have very specific husbandry needs and, if those needs are not met, are prone to a variety of illnesses and disorders. Some of the more common problems include ball pythons who are picky eaters and refuse food, iguanas who do not properly digest their food because of temperatures, boas who become listless and refuse food when it becomes too cold, and many reptiles run the high risk of calcium deficiencies.. Also, people often become un-enamored with their scaly friends when they realize that reptiles do not offer forth the same kind of warmth and affection as their warm-blooded cousins. With more instinctive behaviorisms and smaller ...
The etiology of reptilian viral diseases can be attributed to a wide range of viruses occurring across different genera and families. Thirty to forty years ago, studies of viruses in reptiles focused mainly on the zoonotic potential of arboviruses in reptiles and much effort went into surveys and challenge trials of a range of reptiles with eastern and western equine encephalitis as well as Japanese encephalitis viruses. In the past decade, outbreaks of infection with West Nile virus in human populations and in farmed alligators in the USA has seen the research emphasis placed on the issue of reptiles, particularly crocodiles and alligators, being susceptible to, and reservoirs for, this serious zoonotic disease. Although there are many recognised reptilian viruses, the evidence for those being primary pathogens is relatively limited. Transmission studies establishing pathogenicity and cofactors are likewise scarce, possibly due to the relatively low commercial importance of reptiles, difficulties with
Scientists have discovered a fossil of a new ancient marine animal that resembles present-day dolphins. The said fossil gives a hint of how marine reptiles survived mass extinction 250 million years ago.
The skeleton of an elasmosaur dinosaur, a rare 25-foot-long marine reptile, has been found for the first time in the mountains of Alaska.
The distribution on serovars of 60 Salmonella isolates from reptiles kept in captivity in Denmark during the period 1995-2006 was investigated. The isolates were all recovered from clinical specimens submitted to the National Veterinary Institute. A majority of the samples were from reptiles in zoological gardens or similar, while a minor number was from reptiles kept in private homes. A total of 43 serovars were detected, most of them being what is usually called exotic serotypes, and many not having a trivial name, while a few isolates belonged to well-known human pathogenic serovars, such as S. Enteritidis, S. Typhimurium, S. Bovismorbificans. One isolate was rough and two were non-typeable. Isolates from turtles belonged to the subspecies enterica, while many isolates from both sauria and snakes belonged to other subspecies. The findings underline the potential zoonotic risk by handling reptiles in zoological garden or other public settings, or keeping pet reptiles in private homes ...
Ticks can be removed by grasping them at the point of attachment and slowly pulling their mouth parts out of the reptiles skin.. To eliminate mites, pesticides and medications are used to kill the parasites both on the reptiles body and within the terrarium. Be very careful when using these chemicals around reptiles because they can cause serious illness or death if pets overdose from the medication, drink from contaminated water, or if ventilation is inadequate. Throw out all substrates and cage furnishings that could be harboring mites. Use newspaper as a floor covering throughout the treatment period and then refurnish the cage with mite-free substrates, branches, rocks, hide boxes, etc.. Bot larvae can be removed from their chamber within the skin by gently enlarging their breathing hole and pulling them out with a pair of tweezers. Maggots must be picked out of or flushed from a reptiles damaged skin. If the reptile has open wounds, it should be treated with topical antiseptics. ...

GENERAL INFORMATION. This article provides an introduction to reptilian therapeutics. There are few drug preparations licensed for use in reptiles. Drugs authorized for use in other species or for humans may be administered under the responsibility of the veterinarian. It is important to note that some drugs may be very safe in certain species and fatal in another. For example, ivermectin while apparently safe in most snakes and lizards, causes death in most chelonia.. All reptiles should be accurately weighed before being medicated to avoid overdosage, and during treatment to monitor response.. All reptiles are ectothermic and a change in temperature may have profound influences on drug distribution, metabolism, excretion, and hence elimination half-life. Some therapeutic regimens state a fixed temperature at which the reptile should be held during treatment. The advantage of this approach is that where pharmacokinetic evidence exists the elimination of the drug will be known and constant. ...
Mosasaurs (pronounced mow-sa-sores) arrived five million years after the ichthyosaurs died out and soon replaced plesiosaurs at the top of the food chain. Their fossils show a steady sequence of changes as they evolved from small lizards living on the waters edge to the oceans top predators. They were powerful swimmers with goanna-like bodies, long snouts and forked tongues. Their paddles were formed from soft tissue covering their long finger bones. They used them for steering as their tails pushed them through the water. Unlike ichthyosaurs and plesiosaurs, they kept their scaly skin.. Mosasaurs ate anything: ammonites, fish, turtles, plesiosaurs, other mosasaurs and even sea birds. The only thing a mosasaur had to fear was a bigger mosasaur. Mosasaur skulls with bite marks from other mosasaurs suggest they might have fought each other for food, territory or mates.. They dominated the worlds oceans and inland seas for 30 million years until they went extinct, along with the plesiosaurs, at ...
Between the later part of the Triassic and the very end of the Cretaceous, the seas of the world (and some of its rivers, lakes and estuaries as well) were inhabited by the remarkable group of swimming reptiles known as the plesiosaurs.
British paleontologists say theyve worked with international colleagues to identify fossil remains as those of a new kind of extinct flying reptile.

Introduction. The Biology and Diversity of Extant Reptiles. The word reptile itself does not describe a monophyletic group of vertebrates, like the mammals or birds. It is used to classify a polyphyletic group of animals that are a subset of the larger group of Amniotes. The term is best described through a cladogram: Dr. Paul M. Barrett 2001 The reptiles first appeared in the early Carboniferous, having evolved from labyrinthodont amphibians. They had several distinct advantages over the amphibians that allowed them to flourish during the cold, dry Permian period. These lead them to be the most successful group of vertebrates and this period was referred to as the age of reptiles. They exploited all terrestrial niches, a few marine and even one group took to the air. No other group of vertebrates had ever displayed such diversity and mammals today are their only match. They were the first group of tetrapods to successfully overcome the major problems of terrestrial life, namely desiccation, ...

Substrates commonly used in reptile enclosures include those in the list below. Some of these substrates are inappropriate for some reptiles. Some are inappropriate for all reptiles and are included here so that you will be forewarned against buying them despite pet store recommendations and the implied or explicit wording on product packaging and advertisements.. Substrates should not be collected in the wild as the soil, leaves, sand, gravel, etc., may contain organisms that are harmful to your reptile. Even if you dont use herbicides and pesticides in your yard, these chemicals are transported through the air as both dry and wet deposits, and so contaminate soil, leaves, and the woody parts of plants, even those at some distance from the point of application.. Particulate substrates, even when made from natural or biodegradable products such as plant fibers, should not be used for any lizard who smells with its tongue. Particles become stuck to the tongue and are swallowed. Over time, ...
Drinking. Drinking. As. Thus they pay a price for their efficient water retention.Organisms in different environments utilize different structures in osmoregulation and excretion.Like birds, many reptiles excrete ni-trogenous waste as insoluble uric acid or urate salts (Minnich, 1972).. In all reptiles, birds, and mammals, the process of excretion, water and salt balance and the regulation of pH in body fluids are controlled by the kidneys.Fish utilize kidneys to filter out the wastes from their blood and then use their skin and gills to excrete. excretory system.Reptiles tend to have a broad innate immune response followed by a more moderate adaptive response, and as an ectotherm, their immune response is strongly affected by.I hope this helps you to understand the differences in excretion between humans and reptiles ...

It would be difficult today to find an experienced keeper of captive reptiles who would fail to recognize that there is seldom a requirement for the feeding of live prey. Invariably most captive reptiles readily accept and thrive upon a diet consisting entirely of frozen/thawed food items. This fact has long been known in zoos and other professional animal keeping institutions and it is unfortunate that one can still find people who should know better recommending the feeding of live prey despite the many disadvantages it entails and the corresponding benefits of a diet consisting of frozen/thawed items.. Snakes and many other reptiles are what are known as obligate carnivores, being limited in their diet to consuming other animals. In the wild, this normally means that they are predators, hunting and subduing their own prey although it is not uncommon for them to scavenge when the opportunity presents itself. Many snakes and lizards have been observed feeding upon carrion and this behavior is ...

Reptiles generally reproduce sexually, though some are capable of asexual reproduction. All reproductive activity occurs through the cloaca, the single exit/entrance at the base of the tail where waste is also eliminated. Most reptiles have copulatory organs, which are usually retracted or inverted and stored inside the body. In turtles and crocodilians, the male has a single median penis, while squamates, including snakes and lizards, possess a pair of hemipenes, only one of which is typically used in each session. Tuatara, however, lack copulatory organs, and so the male and female simply press their cloacas together as the male discharges sperm.[113]. Most reptiles lay amniotic eggs covered with leathery or calcareous shells. An amnion, chorion, and allantois are present during embryonic life. The eggshell (1) protects the crocodile embryo (11) and keeps it from drying out, but it is flexible to allow gas exchange. The chorion (6) aids in gas exchange between the inside and outside of the ...

Suture zones, shared regions of secondary contact between long-isolated lineages, are natural laboratories for studying divergence and speciation. For tropical rainforest, the existence of suture zones and their significance for speciation has been controversial. Using comparative phylogeographic evidence, we locate a morphologically cryptic suture zone in the Australian Wet Tropics rainforest. Fourteen out of 18 contacts involve morphologically cryptic phylogeographic lineages, with mtDNA sequence divergences ranging from 2 to 15 per cent. Contact zones are significantly clustered in a suture zone located between two major Quaternary refugia. Within this area, there is a trend for secondary contacts to occur in regions with low environmental suitability relative to both adjacent refugia and, by inference, the parental lineages. The extent and form of reproductive isolation among interacting lineages varies across species, ranging from random admixture to speciation, in one case via ...

Salmonella can often be found in the intestinal tract of reptiles. A reptile with Salmonella can possibly infect its owner.Salmonella in iguanas is a health problem that can affect their owners sometimes more than the reptile itself. Beneficial bacteria, known as probiotics, have long been known to aid the intestinal tract of humans. Now a product is available for salmonella-positive reptiles. Many reptile-related diseases can be traced to the health of the reptiles intestinal tract. A good, well-balanced probiotic offers a safe approach for the gut of reptiles. Many have said that the use of NutriBAC has increased their reptiles appetite, reversed constipation, and stopped regurgitation following feedings. A good probiotic or beneficial bacteria, like NutriBAC, is simply a tool in the husbandry of reptiles and amphibians. NutriBAC is the only probiotic patented for use in reptiles and amphibians ...
Amphisbaenia (called amphisbaenians or worm lizards) is a group of usually legless squamates, comprising over 180 extant species. Amphisbaenians are characterized by their long bodies, the reduction or loss of the limbs, and rudimentary eyes. As many species have a pink body and scales arranged in rings, they have a superficial resemblance to earthworms. While the genus Bipes retains forelimbs, all other genera are limbless. Although superficially similar to the snakes and Dibamidae, recent phylogenetic studies suggest that they are most closely related to the Lacertidae. Amphisbaenians are widely distributed, occurring in North America, Europe, Africa, South America, and the Caribbean. Most species are less than 6 inches (150 mm) long. Despite a superficial resemblance to some primitive snakes, amphisbaenians have many unique features that distinguish them from other reptiles. Internally, their right lung is reduced in size to fit their narrow bodies, whereas in snakes, it is always the left ...
A popular get well card shows a raccoon saying to a snake, You wouldnt get these stomach aches if you chewed your food properly. Vets know, however, that indigestion in snakes and other reptiles often results not from swallowing food whole but from a parasitic infection. The gastrointestinal disease cryptosporidiosis represents a particularly severe problem: although it is rarely otherwise serious in mammals, reptiles seem especially prone to it and the condition is often fatal. Furthermore it is highly contagious, so early diagnosis would represent a good way to limit its spread among reptiles. Unfortunately, though, diagnosis is extremely difficult. Scientists at the University of Veterinary Medicine, Vienna have developed a test for the identification of the cryptosporidia that cause the condition, enabling them to assess its prevalence in pet lizards and snakes. The results are published in the current issue of the Journal of Veterinary Diagnostic Investigation.. Although known for over ...

Children love to explore the great outdoors. Spotting turtles, frogs, lizards and snakes in the wild is fun and can help build an appreciation of the wonders of wildlife. To help keep the experience healthy, parents and guardians should be aware that reptiles and amphibians can harbor Salmonella bacteria that are easily transmitted to people handling them. That includes wild as well as pet store varieties of these animals.. According to the US Centers for Disease Control and Prevention (CDC), Salmonella outbreaks from contact with reptiles and amphibians have caused hundreds of people to become ill in recent years; many of these outbreaks are linked to small turtles. Children under five years old are the most commonly affected, which is why CDC recommends parents prevent their young children from contacting reptiles and amphibians. CDC notes, in fact, that since 1975 the Food and Drug Administration has banned the sale and distribution of turtles with a shell length of less than four inches in ...
Clinically healthy reptiles may shed Salmonella and therefore act as a potential zoonotic threat. Most people in Northern European countries are rarely exposed to reptiles, but many zoos have education departments where children have direct contact with this group of animals. The objectives of this study were to determine the prevalence and serotype distribution of Salmonella among reptiles in the Education Department (n = 55) at Copenhagen Zoo and compare it to the Zoos main reptile collection (n = 145) to evaluate the zoonotic risk. Salmonella was isolated from cloacal swabs by selective enrichment, and a single isolate from each positive sample was further identified by biochemical tests and serotyped. The overall prevalence was 35% (69/200) with significant difference between the Education Department (64%, 35/55) and the main reptile collection (23%, 34/145). A total of 28 serotypes were detected. Ten serotypes were isolated from more than one specimen and four from more than one species. ...

Adult male American alligators measure 3.4 to 4.6 m (11.2 to 15.1 ft) in length, and can weigh up to 453 kg (999 lb). Females are smaller, measuring 2.6 to 3 m (8.5 to 9.8 ft) in length. The American alligator inhabits freshwater wetlands, such as marshes and cypress swamps from Texas to southeastern and coastal North Carolina. It is distinguished from the sympatric American crocodile by its broader snout, with overlapping jaws and darker coloration, and is less tolerant of saltwater but more tolerant of cooler climates than the American crocodile, which is found only in tropical climates. American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. Hatchlings feed mostly on invertebrates. They play an important role as ecosystem engineers in wetland ecosystems through the creation of alligator holes, which provide both wet and dry habitats for other organisms. Throughout the year, in particular during the breeding season, American alligators bellow to ...

All reptiles breathe using lungs. Reptiles dont normally breathe through their skin. The only exceptions to this are in aquatic turtles. These animals have developed more permeable skin, and even gills in their anal region, for some species (Orenstein, 2001). Even with these adaptations, breathing is never fully accomplished without lungs. Lung ventilation is accomplished differently in each main reptile group. In squamates the lungs are ventilated almost exclusively by the axial musculature. This is also the same musculature that is used during locomotion. Because of this constraint, most squamates are forced to hold their breath during intense runs. Some, though, have found a way around it. Varanids, and a few other lizard species, employ buccal pumping as a complement to their normal axial breathing. This allows the animals to completely fill their lungs during intense locomotion, and thus remain aerobically active for a long time. Tegu lizards are known to possess a proto-diaphragm, which ...
It turns out that snakes are the most feared of any animal on Earth. Reptiles have had a consistently bad rap for a long time - from the serpent in the Garden of Eden to the basilisk of Lord Voldemort. Reptiles are seen as sinister, scaly, deceitful and more than a bit threatening.. But did you know that rattlesnakes, some of the most feared snakes of North America, bear live young and some actually stay with their young after birth to teach them life habits? That sounds more maternal than threatening! Rattlesnakes (and many other reptiles) are responsible for controlling the population of rodents and insects whose populations would otherwise grow uncontrollably. Snakes and lizards serve as a food source for birds, other reptiles, mammals and even some insects, thus supporting the natural ecosystem that is home to many plants and animals. Climate change is affecting reptiles - which are a vital link in our ecosystems!. Find out more about how rising temperatures are affecting the worlds lizard ...
reptile - Feeding habits: With few exceptions, modern reptiles feed on some form of animal life (such as insects, mollusks, birds, frogs, mammals, fishes, or even other reptiles). Land tortoises are vegetarians, eating leaves, grass, and even cactus in some cases. The green iguana (I. iguana) of Central and South America,...
Ben Creisler [email protected] Some recent (and not so recent) marine reptile papers with free pdfs: Hurum, J.H., Roberts, A.J., Nakrem, H.A., Stenløkk, J.A. & Mørk, A. (2015) The first recovered ichthyosaur from the Middle Triassic of Edgeøya, Svalbard. Norwegian Petroleum Directorate Bulletin 11: 97-110 Stavanger 2014, ISSN Online 1894-7670, ISBN 978-82-7257-117-6. http://www.npd.no/Global/Norsk/3-Publikasjoner/NPD-Bulletin/Bulletin-11-kap/NPD_Bulletin_Hurum_Scr.pdf The Blanknuten Member of the Botneheia Formation preserves ichthyopterygians of various body-sizes. Due to the fragmentary nature of their remains, their systematic positions are controversial. The most complete skeleton of a mixosaur from Svalbard (PMO 219.250) described in this paper adds new data to the Phalarodon-Mixosaurus controversy, which is directly connected to the Svalbard taxa, starting with the description of Ichthyosaurus nordenskioeldii by Hulke in 1873. The ratios of the posterior dorsal vertebrae to the mid ...
The first non-avian reptile genome has been sequenced, that of the North American green anole lizard (Anolis carolinensis). The anole is an emerging model for the study of adaptive radiation and convergent evolution. The genome includes a previously unknown X chromosome, with no homology to known amniote sex chromosomes, and microchromosomes that share a common ancestry with those in birds, but without their unusual characteristics. The evolution of the amniotic egg was one of the great evolutionary innovations in the history of life, freeing vertebrates from an obligatory connection to water and thus permitting the conquest of terrestrial environments1. Among amniotes, genome sequences are available for mammals and birds2,3,4, but not for non-avian reptiles. Here we report the genome sequence of the North American green anole lizard, Anolis carolinensis. We find that A. carolinensis microchromosomes are highly syntenic with chicken microchromosomes, yet do not exhibit the high GC and low repeat content
Reptile Medicine and Surgery in Clinical Practice PDF. The word herpetology is from Greek herpeton, creeping animal and ‐logia knowledge. It is the term used to describe the study of reptiles and amphibians. Some sources describe those who keep reptiles as herpetoculturists and the hobby as herpetoculture.
I HAD PLANNED on covering the article on the platypus genome that came out in Nature last week, but since then this paper has been discussed in detail on Pharyngula and Adaptive Complexity and I think further discussion would be moot. I did notice while reading the paper that the unfortunate description of certain platypus genes as reptilian cropped up frequently. Although the authors noted that the sauropsids and synapsids are amniotes, they never mentioned that platypus genes shared with reptiles are actually basal amniote genes. Although their phylogenetic tree shows synapsids and sauropsids clearly diverging from a common amniote ancestor, they do not seem to realize referring to these ancestral amniote genes as reptilian suggests evolution of the platypus (and thus all synapsids) from reptiles instead of from a non-reptilian amniote. However, today I want to talk about the platypus sex chromosomes. Platypuses, like the therians, have genetic sex determination. They have an XX/XY system ...
Before acquiring a reptile, thoroughly research all aspects of reptile ownership including not only which reptile is appropriate for your lifestyle, but also how to provide it with proper diet, suitable housing, and a healthy, stimulating environment. As a rule, if you want a pet to snuggle with, a reptile is not for you! If, on the other hand, you want an animal you can display in a well-designed, natural habitat, marvel in its natural behaviors, and enjoy learning about it, owning a reptile might be for you. Most reptiles must be fed and watered daily, and often their cages need to be cleaned daily as well. All reptiles need to be examined by a reptile-savvy veterinarian immediately after purchase or adoption (within 48 hours), and then at least annually after that. Since many exotic animals are prey species that hide illness to avoid being captured by predators, these pets usually do not act sick (or show any indication of illness) until they are very sick and need immediate veterinary ...
Freshwater turtles are reptiles, like snakes, crocodilians and lizards. Like other reptiles, they are ectothermic, or cold-blooded, meaning that their internal temperature matches that of their surroundings. They also have a scaly skin, enabling them, as opposed to most amphibians, to live outside of water. Also like many reptile species, turtles lay eggs (they are oviparous). But what makes them different to other reptiles is that turtles have a shell. This shell, composed of a carapace in the back and a plastron on the belly, is made of bony plates. These bones are covered by horny scutes made of keratin (like human fingernails) or leathery skin, depending on the species. All Canadian freshwater turtles can retreat in their shells and hide their entire body except the Common Snapping Turtle (Chelydra serpentina). This shell is considered perhaps the most efficient form of armour in the animal kingdom, as adult turtles are very likely to survive from one year to the next. Indeed, turtles have ...
reptile - Digestive and urogenital systems: The digestive system of modern reptiles is similar in general plan to that of all higher vertebrates. It includes the mouth and its salivary glands, the esophagus, the stomach, and the intestine and ends in a cloaca.

Its been a quiet weekend yet again. I am starting to doubt my ability to find critters to photograph these days. Hopefully its just me and a bit of bad timing because I would hate to think that animal numbers are declining to the point where even the more commonly recorded species are difficult to locate even in relatively undisturbed areas. I spent a few hours in a heath section of a National Park well inland from the coast where in previous years I have photographed quite a few different reptiles and amphibians. The conditions were good, rainfall the night before and warm sunny skies with some cloud cover but it was strangely devoid of life except for the odd bird here and there. Does anyone remember when you couldnt walk along a bush track without disturbing numerous skinks and small dragons which would scuttle away making a racket in the leaf litter. Not sure exactly whats happening now but those days seem to be long gone. Is it just me? I dont know, I certainly hope it is ...

Reptiles and amphibians (herps) represent an important part of aquatic and terrestrial ecosystems. The American Southwest is well known for its abundance and diversity of reptiles. Although this region is less known for its amphibian populations, they too can be quite abundant in some habitats and are good indicators of environmental change due to their sensitivity to a variety of factors such as pollution, introduced species, drought, habitat destruction, and disease. Herp populations may be affected by these factors and exhibit measurable changes in site occupancy, distribution, abundance, and species richness ...

Background Rhamphorhynchus from the Solnhofen Limestones is the most prevalent long tailed pterosaur with a debated life history. Whereas morphological studies suggested a slow crocodile-like growth strategy and superprecocial volant hatchlings, the only histological study hitherto conducted on Rhamphorhynchus concluded a relatively high growth rate for the genus. These controversial conclusions can be tested by a bone histological survey of an ontogenetic series of Rhamphorhynchus. Methodology/Principal Findings Our results suggest that Bennetts second size category does not reflect real ontogenetic stage. Significant body size differences of histologically as well as morphologically adult specimens suggest developmental plasticity. Contrasting the superprecocial hatchling hypothesis, the dominance of fibrolamellar bone in early juveniles implies that hatchlings sustained high growth rate, however only up to the attainment of 30-50% and 7-20% of adult wingspan and body mass, respectively. The
