Otter

Otters possess streamlined bodies and webbed feet perfectly adapted for swimming. Their exceptionally dense fur features a soft underlayer that traps air to keep them warm in freezing temperatures. Most species inhabit freshwater rivers, lakes, and coastal shorelines across the globe. They use their strong, muscular tails to navigate swiftly and steer through turbulent waters. Long whiskers on their snouts help them detect the subtle movements of prey in murky riverbeds. Some marine species even spend their entire lives floating in the vast ocean.
