| These amphibians, like modern frogs and salamanders, hatched from eggs and spent their larval period in the water as tadpoles. |
| In some lepospondyls, and in frogs and salamanders, the surangular is absent. |
| Sirens and amphiumas are large salamanders that may determine community structure through top-down effects. |
| The behavior is presumably similar to the anguilliform swimming of eels and elongate salamanders. |
| While salamanders with ballistic tongue projection rarely miss their target, frogs that use ballistic projection can be highly inaccurate. |
| The familiar frogs, toads, and salamanders have been present since at least the Jurassic Period. |
