| Southern two-lined salamanders
are small and slender and vary from appearing bright yellow to a
rusty orange color. There are two black stripes that run from the
head down the body and well onto the tail. These lines are usually
not as well defined as those of their relatives to the north, the
Blue Ridge two-lined salamander (E. wilderae). Rather,
the lines are frequently sharply defined near the dorsum but are
much less so on the ventral margin. The tail is fairly long, comprising
about half the animal's total length. Southern two-lined salamanders
are rarely seen in the summer, but may by found along the banks
of free-flowing creeks and streams during other times of the year.
Males can be distinguished most of the year (fall to spring) by
the presence of cirri (hence the scientific name), fleshy downward
protuberances from the upper lip resembling a moustache, perhaps.
The cirri are thought to help the male detect chemical signals from
females, and maybe even competing males, during the breeding season.
Females lay their eggs beneath rocks in streams and most often stay
to guard the clutch. After hatching, larvae stay in the stream for
at least a year or two before metamorphosing and becoming semi-terrestrial
adults.
