Dwarf Salamander - Eurycea quadridigitata
Appearance: The Dwarf Salamander is a small, slender salamander that infrequently exceeds 7 or 8 cm. (3 in.) in length despite its very long tail.  Coloration is similar to that of E. cirrigera, although the dorsolateral stripes are broader and cover nearly the whole of each side.  The most distinguishing characteristic of this member of the genus Eurycea is that this is the only species with only four toes on each hind foot.

Habits and Habitat: The Dwarf Salamander is primarily a salamander of the Coastal Plain habitats.  Adults can be found beneath logs, leaves, and other cover objects in moist habitats, although they may occur in more upland areas outside of the breeding season.

Eurycea quadridigitata - Dwarf Salamander - larvaEurycea quadridigitata - Dwarf Salamander - larvaReproduction/Egg Description: Females lay eggs in standing water (small ponds and pools, ditches) or sometimes in dry depressions in late fall or early winter.  Eggs are usually laid singly and are attached to twigs or other pieces of vegetation. Eggs that are laid in dry depressions hatch shortly after inundation.

Distribution and Abundance: The Dwarf Salamander inhabits the Coastal Plain of the southeastern United States from North Carolina around the Gulf of Mexico to east Texas. This is a common salamander where its habitat requirements are met.

SE ARMI Index Sites: Okefenokee National Wildlife Refuge.
