Animal pelage refers to the fur, hair, or wool that covers the bodies of mammals. This outer layer serves several important functions, including insulation, protection from the environment, and camouflage. The type and texture of pelage can vary widely among species, adapting to their habitats and lifestyles. Pelage can also change with the seasons, as many animals grow thicker fur in winter for warmth and shed it in summer to stay cool. The coloration of pelage often plays a crucial role in predator-prey dynamics, helping animals blend into their surroundings or stand out for mating displays.
