Length 4 – 6 1/2 in. (10-16.5 cm). This is a strikingly beautiful salamander with a distinctive long tail. The tail accounts for more than half the total length of the mature adult while young salamanders have relatively short tails. For the most part, the Long-tailed Salamanders are restricted to heavily wooded, hilly regions. They prefer wet shale banks and other seep areas. They are most often found hiding under stones or logs. They may also be encountered under such objects along clear, flowing woodland streams. Little is known about the life history of the Long-tailed Salamander, but it probably closely parallels that of other members of the same genus, such as the Two-lined Salamander.
