Fur

Fur refers to the coat of hair covering the skin of many animals. It serves multiple purposes including protection, insulation, and sensory input. The characteristics of fur can vary widely among different species. Fur helps to protect animals from the elements, such as cold weather and harsh sunlight. It also provides a layer of insulation, keeping animals warm in cold environments. Additionally, fur can serve as a sensory organ, helping animals to detect changes in their environment. The texture, color, and density of fur can vary greatly depending on the species and their habitat. For example, animals living in colder climates tend to have thicker, denser fur, while those in warmer climates may have shorter, lighter fur. See Skin for more details.
