Sea otters don’t have blubber like other marine mammals — instead, they rely on the densest fur of any animal on Earth to stay warm! With up to 1 million hairs per square inch, their fur traps tiny pockets of air that act like a cozy insulation layer, even in freezing ocean temperatures. They spend hours each day grooming to keep their fur clean and fluffy — because if it’s not in perfect condition, they can’t stay warm. It’s a full-time job being this adorable! | Cincinnati Zoo & Botanical Gard
