Caecilians (/ s ɪ ˈ s ɪ l i ə n /; New Latin for 'blind ones') are a group of limbless, vermiform (worm-shaped) or serpentine (snake-shaped) amphibians with small or sometimes nonexistent eyes. They mostly live hidden in soil or in streambeds, and this cryptic lifestyle renders caecilians among the least familiar amphibians.
Turtles, snakes, lizards, and crocodilians are all represented as U.S. state reptiles. In terms of common divisions of reptiles, turtles are most popular. Fifteen of the twenty-seven states give them official status. [nb 1] [nb 5] The rest of the state reptiles comprise four snakes, [nb 6] five lizards, [nb 7] and three crocodilians.
The viperine water snake or viperine snake (Natrix maura) is a semiaquatic, fish-eating natricine water snake. Despite its common names, it is not a member of the subfamily Viperinae . It was given its common names due to exhibiting a dorsal colour pattern that superficially resembles that of sympatric adder species.
The amphiuma's predatory behaviors and food selection are very calculated and variable depending on abundance of food. In addition to eating frogs, snakes, fish, crustaceans, insects, and other amphiuma, amphiuma have been found to eat annelids, vegetables, arachnids, mollusca, and larvae. [12] Amphiuma seem to have a preference for eating ...
The grass snake is widely distributed in mainland Europe, ranging from mid Scandinavia to southern Italy. It is also found in the Middle East and northwestern Africa. Grass snakes in Britain were thought to belong to the subspecies N. n. helvetica but have been reclassified as the barred grass snake Natrix helvetica.
Here we report the findings of the second Global Amphibian Assessment, evaluating 8,011 species for the International Union for Conservation of Nature Red List of Threatened Species. We find that amphibians are the most threatened vertebrate class (40.7% of species are globally threatened).
Stokes's sea snake is one of the heaviest and stoutest seasnakes, with the longest fangs of any marine snake. [4] Its fangs are long enough to pierce a wetsuit. [5] Its mid-ventral scales are enlarged to form a distinct keel on its belly, the keel frequently broken up into two wart-like tubercles. [6]
The largest living amphibian is the 1.8 m (5 ft 11 in) South China giant salamander (Andrias sligoi), but this is dwarfed by prehistoric temnospondyls such as Mastodonsaurus which could reach up to 6 m (20 ft) in length. The study of amphibians is called batrachology, while the study of both reptiles and amphibians is called herpetology.
