A sea otter baby is like a cork in the water. It is helpless on the surface of the ocean. Fortunately, otter pups have smart moms, who have invented some clever ways to keep their little ones from drifting away.

Video Summary

When sea otter babies are born, they are not capable of directional swimming.  They simply float in the water, because their dense fur retains so much air. Pups are completely at the mercy of sea currents. This presents a problem when mom otters need to leave their babies to go hunting. Left unanchored, the baby otter will simply float away. To prevent this scenario, mom otters will often wrap their pups in seaweed. Clever sea otters will even use man-made structures as playpens to keep pups safe.
