Identifying Characteristics

Holbrook’s Southern Dusky Salamander is brown to black with 1–2 rows of white spots on each side. The belly is gray-brown to black with small white speckles. The tail is laterally compressed, sharpening towards the tip. Like all Dusky Salamanders, there is a light stripe from each eye extending backwards to the base of the jaw.

Did You Know?

Unlike pond-breeding salamander larvae that have nonfunctional limbs, stream breeding salamanders have fully functional limbs.

Role in the Web of Life

These nocturnal predators consume a variety of small invertebrates and are also known to be cannibalistic. Mating probably occurs in spring with females laying 9–20 eggs in cavities near water in late spring to summer. Females remain with the nest until eggs hatch in the fall. Metamorphosis occurs the following spring.

Conservation

Species appears to be secure in Virginia.
