Abstract

Many species of amphibians and reptiles shed and sometimes consume all or part of the slough (dermatophagy). However, detailed accounts of these behaviors are lacking. The potential relationship between sloughing and social behavior in amphibians is largely unexplored. Herein, I describe 4 observations of shedding and 1 of dermatophagy during courtship for 2 species of lungless salamanders (Family Plethodontidae): Desmognathus valentinei (Valentine's Southern Dusky Salamander) and Desmognathus conanti (Spotted Dusky Salamander). Two of the salamanders were recently inseminated females and each lost a sperm cap during shedding. I explore multiple hypotheses for the potential relationship between courtship and shedding in lungless salamanders, including the possibility that shedding serves as a means of cryptic female choice.
