See What Sea Otters Do When No One’s Looking

It’s not hard to drum up love for sea otters with their furry little paws, inquisitive expressions, and playful demeanor. But despite the attention and money lavished on this marine mammal, they still have a long way to go.

Campaigns such as the current Awareness Week—which runs from September 20 to 26—aim to help people see past the adorable surface of a and into the deeper conservation issues these animals face.

The fur trade decimated sea populations starting in the 1700s, eventually exterminating them from most of their historic range. They once stretched from Japan through Russia across to Alaska and down into Baja California.

By the early 1900s, the sea otter was thought to be extinct off of California. However, in the 1930s, people started seeing a small group of them near Big Sur (shown above).

Some population counts revealed about 50 otters along the central California coast, says Michael Harris, a sea otter biologist with the California Department of Fish and Wildlife who is based in Morro Bay near San Luis Obispo.

“They formed the parent population of what we have today,” he says.

Now two subspecies inhabit coastlines from the Kuril Islands (map) in Russia over to the Aleutian Islands and down into Washington state, while the third lives off of California.

If you’ve ever wondered what these furry marine mammals do all day, look no further than the following seven pictures.

Northern Cousins – The northern sea otter, shown here in Kodiak Island, Alaska, is doing better than their southern cousins, says sea otter expert Michael Harris. This is partly because the northern otters have more room to expand their populations. Photograph by Roy Toft, National Geographic Creative
Dive! Dive! Dive! Another reason southern sea otters (pictured) are struggling is the great white shark, says Harris. “The last ten years, the biggest impact to the California population has been mortality related to white shark bites,” he says.

Dinner – Sea otters are important parts of the kelp forest ecosystem off of California. They prey on animals including crabs (pictured) and help keep urchin populations in check so that the spiky animals don’t mow down kelp forests. Photograph by Norbert Wu, Minden Pictures
