Eastern long-tailed salamander

The Eastern long-tailed salamander is a species of lungless salamander found in the Appalachian Region and Ohio River valley of the eastern United States. It is characterized by its yellow to orange-red body, often adorned with black spots, and a notably long tail. This salamander is commonly found in cave twilight zones, springs, and surrounding forests.

About Eastern long-tailed salamander

The Eastern long-tailed salamander, scientifically known as Eurycea longicauda, is a species of lungless salamander native to the Appalachian Region and Ohio River valley in the eastern United States. Its common names include the long-tailed salamander and longtail salamander.

Physical Characteristics and Habitat

This salamander is recognized by its variable body coloration, which ranges from yellow to orange-red or red, often adorned with random black spots. A defining characteristic is its long tail. It typically measures around 50 mm (2.0 inches) in snout-vent length (SVL) with a tail length of approximately 72 mm (2.8 inches).

The Eastern long-tailed salamander is an adaptable species, inhabiting a variety of environments. It is commonly found in the twilight zones of caves, as well as in springs and the surrounding forest. Its preferred habitats also include streamsides, spring runs, ponds, cave mouths, and abandoned mines. During periods of wet weather, they may venture into wooded terrestrial areas, often seeking shelter in rock crevices or beneath rocks and logs.

Reproduction and Life Cycle

Reproductive activities for at least one subspecies, E. l. melanopleura, occur between November and February. Eggs, measuring about 7 mm (0.28 inches) in diameter, are laid in underground crevices associated with aquatic environments, and in caves, they may be attached to objects in or above water. The larvae hatch in January to March at approximately 10 mm (0.39 inches) SVL and undergo metamorphosis about seven months later, when they reach a size of 23–28 mm (0.91–1.10 inches) SVL. Sexual maturity is reached at SVLs between 31–43 mm (1.2–1.7 inches) for males and 33–43 mm (1.3–1.7 inches) for females.

Conservation Status

The overall population of the Eastern long-tailed salamander is considered large, likely exceeding 100,000 individuals. While some localized populations may experience impacts from activities such as strip mining and acid drainage from coal mining, there are no major overarching threats to the species. Furthermore, its geographic range overlaps with several protected conservation areas, contributing to its continued presence.
