What kind of sharks eat sea otters?
In this manner, sea otters are keystone predators in the kelp forests where they live. They are not at the top of the food web, however, and are eaten by orcas, great white sharks and other large predators.

Do sharks attack sea otters?
In the 1930s, a century after the fur trade nearly wiped out California’s iconic sea otters, a few dozen stragglers were discovered swimming below the rugged crags of Big Sur, south of Monterey Bay. White sharks now kill so many otters that it threatens to hamper their recovery.
