Growth and Metamorphosis of Larval Red Salamanders (Pseudotriton ruber) On the Coastal Plain of South Carolina

Raymond D. Semlitsch

 

Abstract

Larval development of the red salamander, Pseudotriton ruber, is described for two populations on the Upper Coastal Plain of South Carolina.  The smallest larvae, presumably hatchlings, were collected in January 1979 and 1980 and measured 11.2-13.5 mm in snout-vent length (SVL).  Estimates of growth for the first 6 mo of life ranged from 1.2 2.0 mm/mo based on field collections and 2.8 mm/mo from experimental cages.  Most larvae metamorphosed from June through November, 18-23 mo after hatching.  The period of larval development was shorter than described for populations in the Blue Ridge and Piedmont Psysiographic Provinces of North and South Carolina.  Size of larvae at metamorphosis ranged from 45.5 50.0 mm SVL.  The maximum size of larvae and size at metamorphosis were significantly larger than reported for Blue Ridge and Piedmont population.
