What is the body covering of a platypus?

The body covering of a platypus is fur. Platypuses have dense, water-resistant fur that helps them stay warm and dry in their aquatic environment. The fur is made up of two layers: a shorter, dense undercoat, and a longer, coarser outer coat. The undercoat traps air and provides insulation, while the outer coat helps to shed water. The fur also helps the platypus camouflage itself in its surroundings.
