Everything about Red salamander.
Pseudotriton ruber is a medium-large salamander, with adults ranging from 4. 3 to 7. 1 in (11–18 cm) in total length. 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. 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. Mud salamanders typically have a blunter snout than the red salamander. Also, the mud salamanders typically have a more contrasting dorsal and ventral coloration than the red salamanders that are more uniform in color.
