Sea otters are very good swimmers. They can spend their whole lives in the water though they may occasionally haul out on land to rest. However, they are very clumsy on land and won’t venture more than a few yards away from water.
Sea otters are very social animals. They sometimes
travel in groups and may gather together to rest.
Concentrations of over 1,000 animals have been seen
floating together in a single area.
Breeding males are territorial and defend areas where
females are concentrated. They will drive other males out
of their territory. Nonbreeding males may form their own
groups in an area just outside the breeding territory.
Sea otters do not undergo long distance migrations. They
generally remain in a home range that may be a few square
km up to 40 km2.
