The numbers of species cited above follows Frost and the total number of known (living) amphibian species as of March 31, 2019, is exactly 8,000, [11] of which nearly 90% are frogs. [ 12 ] With the phylogenetic classification, the taxon Labyrinthodontia has been discarded as it is a polyparaphyletic group without unique defining features apart ...
List of amphibians. The temnospondyl Eryops had sturdy limbs to support its body on land. Red-eyed tree frog (Agalychnis callidryas) with limbs and feet specialised for climbing. Japanese giant salamander (Andrias japonicus), a primitive salamander. The bright colours of the common reed frog (Hyperolius viridiflavus) are typical of a toxic species.
The axolotl (/ ˈæksəlɒtəl / ⓘ; from Classical Nahuatl: āxōlōtl [aːˈʃoːloːtɬ] ⓘ) (Ambystoma mexicanum) [3] is a paedomorphic salamander closely related to the tiger salamander. [3][4][5] It is unusual among amphibians in that it reaches adulthood without undergoing metamorphosis. Instead of taking to the land, adults remain ...
Amphibious fish are fish that are able to leave water for extended periods of time. About 11 distantly related genera of fish are considered amphibious. This suggests that many fish genera independently evolved amphibious traits, a process known as convergent evolution. These fish use a range of methods for land movement, such as lateral ...
A few of the larger ones may eat other frogs, small mammals and reptiles, and fish. [160] [161] A few species also eat plant matter; the tree frog Xenohyla truncata is partly herbivorous, its diet including a large proportion of fruit, floral structures and nectar.
Large species such as the Japanese giant salamander (Andrias japonicus) eat crabs, fish, small mammals, amphibians, and aquatic insects. [38] In a study of smaller dusky salamanders ( Desmognathus ) in the Appalachian Mountains , their diet includes earthworms , flies , beetles , beetle larvae, leafhoppers , springtails , moths , spiders ...
"You literally can look down the shoreline and see 50 frogs on one side and 50 on the other and in the water you see 100 to 1,000 tadpoles. It’s a completely different lake," he said. The fish ...
[17] [18] Unlike other modern amphibians (frogs and salamanders) the skull is compact and solid, with few large openings between plate-like cranial bones. The snout is pointed and bullet-shaped, used to force their way through soil or mud. In most species the mouth is recessed under the head, so that the snout overhangs the mouth. [10]
