NATURAL HISTORY

Habitat

Notophthalmus viridescens breeds in ponds. Breeding ponds are limited within the Park, being concentrated in Cades Cove and nearby Big Spring Cove (the four Finley-Cane sinkhole ponds), the Cane Creek drainage, and at scattered localities between Sugarlands and Cades Cove along Little River (at the Sinks and ditches along the road to Tremont). These locations are on the Tennessee side of the Park. Although beaver ponds are found in Bone Valley and Big Cove in North Carolina, and small scattered ditches and wetlands occur in Cataloochee Valley, no pond salamanders are known to breed in them.

The life cycle of semi-aquatic salamanders takes place in and near water, as well as, above and below ground. Surface activity is only a small part of their life cycle. Most species probably have a small ground surface home range beneath debris and litter. They spend a significant part of their lives underground. Species occasionally become arboreal during the night or under rainy conditions; often finding shelter under loose bark. As young juveniles, they may remain nearly entirely underground. As adults, they may spend long intervals on the surface feeding and guarding territory.

Cold, heat, and drought generally keep salamanders under cover, conversely heavy rains and high humidity tend to bring them to the surface. They often leave cover when the soil is moist or at night, when they forage.

Reproduction

All semi-aquatic salamanders deposit their eggs in water. Adults may migrate at the same time to breeding sites, despite being constrained to one or a few nights during the breeding season. Males and females may not stay at breeding sites for equal amounts of time, even if the breeding season is extended.

Larvae

Pond larvae have stout bodies, long filamentous gills, and a wide dorsal fin which extends onto the body. They use the extra surface area of the body and fin as swimming aids.
