Processes are characteristic of reptiles.

Reptiles (turtles, crocodiles, lizards and snakes) all terrestrial vertebrates are characterized by molting processes, accompanied by a change in the epidermis (skin), a low level of metabolism and inconsistent body temperature, regeneration, which is well expressed, for example, in lizards. The phenomenon of self-mutilation appears due to a protective reflex, which allows one to escape from a predator, due to a strong muscle contraction, since one of the tails breaks and falls off, over time the lost part is restored.
