Beaver scrubbing fur

Beavers have a dense, waterproof coat of fur that consists of two layers: a soft, insulating underfur and longer, coarse guard hairs. To keep their fur in optimal condition, beavers groom themselves by using their teeth and claws to remove dirt, debris, and loose fur. This self-grooming helps to maintain the waterproof quality of their fur, which is crucial for their survival.

The waterproofing ability of a beaver's fur is essential because beavers spend a significant amount of time in the water. They build dams and lodges in aquatic environments, and having waterproof fur helps them stay buoyant and insulated from the cold water. Additionally, the waterproofing properties of their fur play a role in trapping a layer of air close to their bodies, providing extra insulation.

So, while beavers don't wash in the way humans do, their grooming behavior is essential for maintaining the functionality of their waterproof fur and adapting to their semi-aquatic lifestyle.
