Beavers Can Hold Their Breath for 15 Minutes Underwater. They have a large flat tail that helps them steer through the water. They also have clear eyelids that make it possible for them to open their eyes underwater. These animals can stay under water for as long as 15 minutes because of their specially adapted lungs. Beavers have wide, hairless, flat tails.
