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.

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.
