Pond rules: Paddle like no one's watching 💧 These little loggers are some of the best swimmers around, with some un-beaver-lievable adaptations that make them suited to a semi-aquatic lifestyle. Beavers have extra eyelids that work like built-in goggles, their noses and ears plug underwater, and they can hold their breath for up to 15 minutes. Not only that, but their webbed back feet and paddle-shaped tails help them propel and steer through the water, while thick fur and waterproofing oils keep them warm and dry. #beaverweek2026 #sandiegozoo #beavers
