This is a small salamander (up to 10 cm total length) that lives in clear, cold, mountain streams. It is medium to dark brown and may have a few small light spots on the sides and small dark spots on the tail; it is bright yellow on the belly, usually with some dark spots. Torrent salamanders typically have short snouts and relatively large eyes.
They are very sensitive to desiccation and warm temperatures. More than 83 °F (28 °C) can be fatal, and they can only tolerate a water loss of 19.4 percent of initial body weight at most (compared to 29.0 to 32.9 percent for other species). Because of this, they are rarely found more than a meter away from free-running water.

[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.

Red salamanders eat insects, earthworms, spiders, small crustaceans, snails, and smaller salamanders. To eat, they extend their tongue to capture prey on the tip of it and retract it back into their mouths. [3] The red salamander, as a member of the family Plethodontidae (lungless salamanders) lacks lungs and respires through its skin. [4]
The amphiuma's predatory behaviors and food selection are very calculated and variable depending on abundance of food. In addition to eating frogs, snakes, fish, crustaceans, insects, and other amphiuma, amphiuma have been found to eat annelids, vegetables, arachnids, mollusca, and larvae. [12] Amphiuma seem to have a preference for eating ...
