Length 4 1/2 – 7 1/2 in. (11.5-14 cm). Named for its conspicuously small mouth, this animal also has a relatively small, narrow head. Its dark earth- tone color may be accented with light flecks of pigment, especially along its sides and bottom. The Small-mouthed Salamander is one of the least particular in its choice of habitat. It can be found in just about any situation throughout all but the extreme eastern edge of the state, and like most members of this family it breeds in temporary ponds and wetlands.
