Biting and Vocalization as Antipredator Mechanisms in Terrestrial Salamanders
Preview not available

Abstract

Biting acocmpanied by the exhibition of white mouth lining and audible snapping of the jaws by Desmognathus quadramaculatus effectively repels predatory attacks by the shrew Blarina brevicauda. In other species of terrestrial salamanders vocalizations are present in species which also have noxious or toxic skin secretions. A predator that relies on hearing to locate prey could learn to avoid these vocalizations.
