They are different from other lungless salamanders.

With one highly notable exception, all are members of the family Plethodontidae ("lungless salamanders").

In many species of frog and in most lungless salamanders (Plethodontidae), direct development takes place, the larvae growing within the eggs and emerging as miniature adults.

Adult lungless salamanders have four limbs, with four toes on the fore limbs, and usually with five on the hind limbs.

In the lungless salamanders, muscles surrounding the hyoid bone contract to create pressure and actually "shoot" the hyoid bone out of the mouth along with the tongue.

Lungless salamanders use a similar method, however, both the tongue and underlying hyoid bone project (in contrast to chameleons, whose hyoid remains fixed while the fleshy portion of the tongue projectes).

This species is a member of the Plethodontidae family.

There is little diversity within Plethodontidae in regards to mating.

The only species with which it is likely to be confused are cave salamanders in the family Plethodontidae.

Certain species in the Plethodontidae have a weak zone at the base of the tail and use this strategy readily.
