Quick Summary

The term "juvenal pelage" refers to the first coat of hair on a young mammal. This initial coat is typically fine in texture, similar to an adult's underfur, and is eventually replaced by an adult coat through a process called a postjuvenile molt.1

Pelage, in general, is the hairy, woolly, or furry covering of a mammal, distinct from the skin beneath. It serves several important functions:2
* Insulation: Helping to regulate body temperature.21
* Protection: Guarding against injury.2
* Communication: Its coloration and patterns can aid in species recognition, camouflage from predators, or attracting mates.21

The skin of mammals, including the pelage, is composed of an epidermis and a dermis, which work together to protect the body and interact with the environment.1
