1. Protection: Body coverings provide a protective barrier against environmental factors, such as temperature extremes, UV radiation, and physical damage from sharp objects or predators. For example, fur or feathers insulate animals in cold climates, while scales or shells protect against dehydration in hot, dry environments.
2. Camouflage: Body coverings can also serve as camouflage, helping animals blend in with their surroundings to avoid predators or prey. Many species have coloration or patterns that mimic their habitats, such as the green coloration of frogs and lizards that live in foliage.
