Growth and Metamorphosis of Larval Dwarf Salamanders (Eurycea quadridigitata)

Raymond D. Semlitsch

 

Abstract

Growth of larval dwarf salamanders, Eurycea quadridigitata, is described for two populations on the upper Coastal Plain of South Carolina.  The smallest larvae were collected in early February and were 6.4-6.8 mm in snout-vent length (SVL).  After a 5-6.5 month larval period, larvae transformed at a SVL range of 20.7-25.6 mm.  Larvae from Flamingo Bay transformed at significantly larger SVLs and appeared to mature earlier than those at Karenís Pond.  The sex ratio did not differ from 1:1 and sexual dimorphism in SVL was not evident in newly transformed larvae.  Maturity is presumably attained 8-9 months after hatching in September or October.

Key words:  Amphibia; Caudata; Plethodontidae; Eurycea; Growth; Larval period; Metamorphosis
