THE aposematically coloured eft stage of the red spotted newt, Notophthalmus viridescens viridescens, is both toxic and noxious to potential predators. The black chinned red salamander, Pseudotriton ruber schencki, is the most common red-orange salamander other than eft N. v. viridescens in the vicinity of the Highlands Biological Station in North Carolina. This study provides experimental evidence that P. r. schencki is a Batesian mimic of N. v. viridescens.

An Experimental Study of Batesian Mimicry Between the Salamanders Plethodon jordani and Desmognathus ochrophaeus
TLDR
Experimental predators (chickens) showed neither increased avoidance nor increased attack latency in single salamander presentations of models and non-Mimics, however, some chickens showed reduced preference for both models and mimics compared to non-mimics.
Molecular Identification of an Avian Predator of Mimetic Salamanders
Abstract - Natural field observations of salamander predation are uncommon, in some cases limiting the ability of scientists to study the evolution of toxicity, aposematism, and mimicry in these…
Experimental Support for Aposematic Coloration in the Salamander Ensatina eschscholtzii xanthoptica: Implications for Mimicry of Pacific Newts
Abstract A field experiment was conducted to test the hypothesis that the plethodontid salamander Ensatina eschscholtzii xanthoptica benefits from aposematic coloration. Under field conditions, clay…
Larvae of the predaceous diving beetle Dytiscus verticalis acquire an avoidance response to skin secretions of the newt Notophthalmus viridescens.
TLDR
Larvae of the predaceous diving beetle Dytiscus verticalis acquired an avoidance of the unpalatable newt Notophthalmus viridescens, and this acquired avoidance by a major aquatic insect predator might explain the selective advantage of kinship aggregations in unpAlatable larvae of amphibians.
Rib Penetration and Associated Antipredator Adaptations in the Salamander Pleurodeles waltl (Salamandridae)
TLDR
The sharp rib tips of Pleurodeles waltl penetrate the lateral warts which do not contain granular glands and allow them to act synergistically in repelling predators.

An Investigation into Tetrodotoxin (TTX) Levels Associated with the Red Dorsal Spots in Eastern Newt (Notophthalmus viridescens) Efts and Adults
TLDR
Investigating the concentration of tetrodotoxin in sections of skin containing and lacking red dorsal spots in both Eastern newt efts and adults found no difference between the concentrations of TTX in the red spots as compared to neighboring skin lacking these spots in either efts or adults.

PREDATOR PERCEPTION OF BATESIAN MIMICRY AND CONSPICUOUSNESS IN A SALAMANDER
TLDR
The expectation that the visual abilities of predators may influence the evolution of Batesian mimicry is confirmed, but the role of conspicuousness may be more complex than previously thought.
