What animal holds hands when they sleep to stick together?

What animal holds hands when they sleep to stick together? Sea otters do. They sometimes join paws while resting at the water’s surface, helping keep a mother and pup—or members of a group—from drifting apart in currents.

Sea otters often sleep in groups called rafts. To stay together, they may also wrap themselves in kelp, which acts like a natural anchor. Their dense fur provides insulation because, unlike many marine mammals, sea otters lack a thick layer of blubber. Grooming that fur is therefore essential: trapped air in the fur helps keep cold water away from the skin.

The hand-holding behavior is real but not constant, and it is not an unbreakable rule for every sleeping otter. The animals may rest alone, use kelp, or simply float near one another. A common mix-up is confusing sea otters with seals or river otters; this famous floating behavior belongs specifically to sea otters.
