[15] [16] The common mudpuppy never leaves its aquatic environment and therefore does not undergo morphogenesis; however, many salamanders do and develop differentiated teeth. [17] Aquatic salamander teeth are used to hinder escape of the prey from the salamander; they do not have a crushing function. [17] This aids the salamander when feeding.

Ambystoma talpoideum, the mole salamander, is a species of salamander found in much of the eastern and central United States, from Florida to Texas, north to Illinois, east to Kentucky, with isolated populations in Virginia and Indiana.

The Georgetown salamander is active year-round. The Georgetown salamander is believed to reproduce in the winter, as many other Eurycea species do. [5] [7] The salamanders produce an estimated 30 to 50 eggs per clutch, but likely lay them individually. The hatchlings are about 1 cm long and grow rapidly until they reach a head-trunk length of ...
The Barton Springs salamander prefers clear water and are typically found near openings of springs. [8] These salamanders can also be found under rocks or gravel, within aquatic vegetation, and algae. [4] Barton Springs salamanders can live in water depths ranging from 0.1 to 5 metres (0.33 to 16.40 ft). [4]
Axolotls may be confused with the larval stage of the closely related tiger salamander (A. tigrinum), which are widespread in much of North America and occasionally become paedomorphic, or with mudpuppies (Necturus spp.), fully aquatic salamanders from a different family that are not closely related to the axolotl but bear a superficial ...

Hunting tiny snails, shrimp, and other aquatic ...
