Genetic evidence and some anatomical details (such as pedicellate teeth) support the idea that frogs, salamanders, and caecilians (collectively known as lissamphibians) are each other's closest relatives. Frogs and salamanders show many similarities to dissorophoids, a group of extinct amphibians in the order Temnospondyli. Caecilians are more ...
Frogs can distinguish between low numbers (1 vs 2, 2 vs 3, but not 3 vs 4) and large numbers (3 vs 6, 4 vs 8, but not 4 vs 6) of prey. This is irrespective of other characteristics, i.e. surface area, volume, weight and movement, although discrimination among large numbers may be based on surface area. [170]
Some amphibians such as newts and salamanders, and some frogs such as fire-bellied toads and wood frogs. Some reptiles such as crocodilians, turtles, water snakes and marine iguanas. Waterbirds, especially penguins, waterfowls, storks and shorebirds. Some rodents such as beavers, muskrats and capybaras.

Blue poison dart frog. Herpetology (from Greek ἑρπετόν herpetón, meaning "reptile" or "creeping animal") is a branch of zoology concerned with the study of amphibians (including frogs, salamanders, and caecilians (Gymnophiona)) and reptiles (including snakes, lizards, turtles, crocodilians, and tuataras).
Snakes and legless lizards have evolved the complete loss of their limbs. The upper jaw of Squamates is movable on the cranium, a configuration called kinesis. [28] This is made possible by a loose connection between the quadrate and its neighboring bones. [29] Without this, snakes would not be able consume prey that are much larger than ...
Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes , anteriorly-attached tongue , limbs folded underneath, and no tail (the tail of tailed frogs is an extension of the male cloaca).
The third fable involves a group of frogs that are dissatisfied with the king that Zeus has given them, an inanimate log, and who are then punished with a new King Stork (a water-snake in some versions) who eats the frogs. [56] [57] King Stork has subsequently entered the English language as a term for a particularly tyrannical ruler. [58]
