Sea otters hold hands while they sleep so they don't drift apart. They live in kelp forests off California and Alaska, and when they nap on their backs, they form rafts, sometimes over 100 otters linked paw to paw. Mothers also wrap pups in kelp to anchor them while diving for urchins. This hand-holding, called rafting, keeps families together in currents. Otters have the densest fur of any mammal, up to a million hairs per square inch, and must eat 25% of their body weight daily to stay warm. Survival looks like friendship.
