The North American beaver is one of two beaver species that are still extant. They are semi-aquatic animals with a pair of webbed hind feet and paddle-shaped tails to swim efficiently in water, but they also have front paws with unwebbed claws used for digging.
North American beavers are outstanding swimmers who can stay submerged in water for up to 15 minutes! They are also excellent engineers, as they can build sturdy lodges to serve as shelters. They also build dams to slow down the river flow and flood the area, providing them with safe access to essential supplies. The largest beaver dam ever discovered in Wood Buffalo National Park spans over 850m (0.53 miles) in length!
