Sea otters (Enhydra lutris) form communal resting groups called “rafts,” which can comprise anywhere from a few individuals to several hundred. When sleeping while floating on their backs, otters frequently hold paws with a partner or their pup to prevent tidal ocean currents and rolling waves from separating them out into the open sea. They also wrap strands of giant kelp (Macrocystis pyrifera) around their torsos to anchor themselves securely to the seafloor.
