The beaver’s tail serves multiple purposes—it’s a “rudder” for swimming, a danger signal (beavers slap the water violently with their tails when alarmed), and even a makeshift “stool.” When gnawing on trees near the water, beavers often prop themselves up on their tails while bracing their front paws against the trunk.

But that’s not all—the tail is also an excellent thermoregulator. Its surface is packed with blood vessels that expand in hot weather, allowing blood to flow more easily and cool the animal’s body, which is wrapped in a dense fur coat.
