Sea otters are keystone species i.e. they help in conserving the underwater kelp forests by devouring the sea urchins, thus sustaining one of the world’s most productive ecosystems. These coastal kelp ecosystems provide food source for many marine animals and tiny creatures like sea urchins tend to graze on such forests, disturbing the marine ecosystems.
Sea otter Habitat
Sea otters inhabit shallow coastal waters off the eastern North Pacific. They spend almost their entire life in water and rarely do they come ashore to rest. They are most commonly found in coral reefs and rocky coastlines. However, they can also be found on soft-bottom coastal areas. The northern sea otter tends to haul out more than others.
