sea otters

Floating abalone crackers

Sea otters are marine mammals native to the North Pacific coast, known for floating on their backs and using rocks as tools to crack open shellfish.

Unlike other marine mammals, they lack blubber and rely on extremely dense fur for insulation—the densest of any animal.

They spend most of their lives in the water, often in kelp forests: We watched the sea otters cracking shells on their bellies.
