Sea otters hold hands while they sleep to avoid drifting apart. When resting on their backs, even gentle ocean currents can separate them. Grabbing a buddy turns drifting otters into a floating group nap that stays together.
This behavior is important for mothers and pups. Baby otters are poor swimmers and tend to wander. Holding on keeps pups close and safe, sparing everyone the stress of waking up alone in open water.
This is one of the cutest animal-survival skills I’ve ever seen. I’d like to think the otters in this video are best friends who nap this way daily. I hope they never drift apart.
