Description
Ambystoma jeffersonianum is a long, slender salamander, ranging from 12.1 to 21 cm in length. Long digits and a wide snout help characterize this species. Bluish flecks often are scattered along the limbs and lower sides of the body, complementing the typical dark-brown or dark gray the species usually exhibits. The ventral stomach is lighter in color, usually gray.

This species is primarily located on the East Coast of the United States, ranging from west New England and southern New York to Virginia and Indiana. Typical habitats consist of swamps and ponds of the deciduous forest regions where A. jeffersonianum may often be found under debris.

Life History, Abundance, Activity, and Special Behaviors
During breeding season, which lasts from March to April, adults characteristically migrate to ponds. Cylindrical masses of 10-15 eggs a piece are laid by the female, underwater, and attached to slender twigs. The hatching period will occur 30-45 days later where the larvae are typically 13 mm long. Transformation occurs from the months of July to September where 51 to 71 mm of growth are observed.
