With their expressive faces and soft, furry bodies, sea otters exude charisma. But when it comes to survival, cute and cuddly doesn’t always cut it.

As few as 2,800 sea otters call California’s waters home. The population descends from a single remaining colony of about 50 hidden amid the crags of Big Sur, out of sight from fur hunters who nearly wiped out the world’s entire population by the early 1900s. Today, they are at risk from pollution-caused disease, oil spills and fishing gear.

But even in such small numbers, these marine mustelids—related 
to weasels, ferrets and minks—have a profound influence on the marine ecosystem, keeping crucial kelp forests healthy by eating urchins that can overgraze. The otters’ diverse diet includes clams, crabs and mussels, 
which they cleverly crack open with a rock—every otter keeps one 
tucked away in a chest pouch.

Unlike most of their blubbery brethren, sea otters have fur—the densest of any mammal at up to 1 million hairs per square inch—to keep the chilly waters at bay. Because they can’t afford a bad hair day, much time is spent grooming their “do.” If their fur becomes soiled, it’s no longer waterproof and they can freeze to death. That’s one reason oil spills are so lethal.

Despite these amazing adaptations, California sea otters still need our help to keep their heads above water—so they can frolic and we can be charmed throughout this century and into the next.

Saving Something Wild

Defenders is backing the effort to end a no-otter zone—put in place to address fishing interests—that has prevented California sea otters from expanding into some of their native habitat since 1987. Recently, the U.S. Fish and Wildlife Service determined that allowing the population to naturally expand is the sea otter's best shot at recovery. Defenders also scored an important win for sea otters last year by helping to save the California Sea Otter Fund, which collects donations from state taxpayers who support sea otter conservation. Since 2009, the fund—which supports scientific research to figure out how toxic chemicals and pollution harm otters—has raised more than a million dollars. Defenders supported legislation to renew the fund, which was reauthorized in September.
