The outer covering of an otter consists of a dense layer of fur that serves multiple purposes, including insulation and waterproofing. This fur is composed of two layers: a soft undercoat that retains heat and longer guard hairs that repel water. The unique structure of the fur helps keep otters warm in cold water while allowing them to stay buoyant and agile. Additionally, otters have specialized oils in their skin that help maintain the water-resistant qualities of their fur.
