Sea Otters


Everything you “otter” know

With their soft, dense fur, cute expressions and lazy backstroke, it’s easy to fall in love with the sea otter.

Watch the videos below to learn more about what makes the sea otter so amazing!


Did You Know?

They’re Covered

No need for a “Hair Club for Otters.” Sea otters have the world’s densest fur … up to a million hairs per square inch. The average human head has 100,000 hairs or less.

Back Floating Fun

Right at home in the water, sea otters sleep, have their pups and even eat while floating on their backs. In fact, they’re built for ocean life. They can close their nostrils and ears underwater and their webbed hind feet help them swim.

The See Food Diet

A sea otter gobbles up about a quarter of its weight in food each day to stay warm in cold water and support its high metabolism. That’s like a 60-pound kid eating 60 quarter-pound hamburgers a day! It might work for an otter, but we DON’T recommend you try it!

Tool Time

Sea otters are one of the few mammals, other than primates, known to use tools. They use small rocks or other objects to pry shellfish from rocks and hammer them open.


To keep their luxurious coats waterproof, otters spend many hours a day cleaning and grooming. Their thick fur, when it’s clean and fluffy, traps a layer of air against their skin and helps protect it from the cold water.

Sticking Together

Sea otters live in loose-knit groups called rafts. Otters in rafts often sleep side-by-side, wrapped in strands of kelp so that they don’t drift far from each other.
