[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.

Though not much is known about an adult salamander's eating habits, [25] it is known that they are likely to feed on earthworms, beetles, spiders, and even smaller kinds of salamanders. [26] Mud salamanders also can eat invertebrates as small as mites. [25] What the mud salamander tends to eat however, mainly lies in the habitat in which it lives.
Unlike other cold-blooded animals like reptiles or frogs, salamanders are active and awake during winter. Winter is a surprisingly busy time of the year for East Tennessee's special salamanders ...
Coeur d'Alene salamanders are known to eat aquatic insects and other invertebrates, which are also active at night. In northern Idaho, P. idahoensis emerges from winter hibernation in late March and is active near the surface through April and May; this surface activity is negatively correlated with both high daytime temperatures and the number ...
The olm (German: ⓘ) or proteus (Proteus anguinus) is an aquatic salamander which is the only species in the genus Proteus of the family Proteidae [2] and the only exclusively cave-dwelling chordate species found in Europe; the family's other extant genus is Necturus.
Many salamanders do not use vocalisations, [70] and in most species the sexes look alike, so they use olfactory and tactile cues to identify potential mates, and sexual selection occurs. Pheromones play an important part in the process and may be produced by the abdominal gland in males and by the cloacal glands and skin in both sexes.
Desmognathus fuscus is a species of amphibian in the family Plethodontidae (lungless salamanders). [2] [3] The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form several distinct species, the southern dusky salamanders (D. auriculatus, D. valentinei).
