otters

Whiskered river mammals

Otters are semiaquatic mammals with sleek bodies, webbed feet, and dense waterproof fur.

They're known for playful behavior—sliding down mudbanks, floating on their backs, using rocks to crack open shellfish.

Sea otters live in coastal waters; river otters inhabit freshwater.

We watched the otters chase each other through the kelp.
