Abstract

Predation on Notophthalmus viridescens viridescens (Red-spotted Newt) is rare due to their toxic skin excretions, which provide chemical defense against potential predators. Here we document the occurrence of the Red-spotted Newt in the stomach contents of Lepomis macrochirus (Bluegill) and L. auritus (Redbreast Sunfish), common sunfishes within an urban watershed in Columbus, GA.
