What predators feed on otters?
In California, great white sharks are sea otters’ primary predators. In
Alaska, killer whales seem to be eating more sea otters, perhaps because their
usual prey (seals and sea lions) are becoming more scarce. Stellar sea lions,
coyotes, bears and eagles have also been known to feed on sea otters.
How do humans harm sea otters?
Humans kill sea otters unintentionally -- by hitting with them with boats
or entangling them in fishing gear -- and intentionally, by shooting them.
