Its skin is orange/red with random black spots. Its habitats are temperate forests, small creeks, ponds, forests, temperate shrubland, rivers, intermittent rivers, freshwater, trees springs. It is threatened by habitat loss. Red salamanders eat insects, spiders and smaller salamanders. The red salamander, as a member of the Plethodontidae family, lacks lungs and respires through its skin. ==Diagnosis== ''Pseudotriton ruber'' is a larger salamander, averaging from long. Its sides and back vary in color from an orange-brownish tint to a bright red depending on its age. Like other salamanders, the red salamander seems to lose its color as it ages, becoming more darkly pigmented with less obscure patterns.〔Conant, R. and J.T. Collins.Peterson Field Guides: Reptiles and Amphibians.New York: Houghton Mifflin, 1998.〕 Another distinguishing characteristic of ''P. ruber'' is the appearance of numerous irregular black spots down its back. Although the red salamander is brilliantly colored and has many distinguishing features, it is sometimes difficult to tell species apart. ''P. ruber'' is most similar in appearance to the mud salamander (''P. montanus''), but can be distinguished by the difference in size and number of spots running down the dorsum and also by the difference in the color of the iris. The red salamander has more spots and the spots also tend to be larger in size than those of the mud salamander. In regard to eye color, the red salamander’s iris is a gold-like tint, whereas the mud salamander’s iris is brown.
