Discover How Fast Polar Bears Can Swim: Top Speeds and Interesting Facts!

Polar bears are not only the largest of the world’s eight living bear species but also the most aquatic. Their scientific name, Ursus maritimus, translates to “sea bear,” and they are officially classified as marine mammals. Polar bears spend their lives in and around the ocean, and as such, they are great swimmers. Read on to find out how fast polar bears can swim, along with other water and land speed stats.

How Fast Can a Polar Bear Swim?

A polar bear’s top swimming speed is 6.2 mph (10 kph). It uses its front feet like paddles and its hind legs and feet like rudders to maneuver in the water.

How Far Can a Polar Bear Swim?

A polar bear’s longest recorded continuous swim was an incredible 426 miles (687km) over 9 days. Unfortunately, polar bears are being increasingly forced into such extreme trips due to melting sea ice, and such feats come at great risk to their physical health and reproductive fitness.

How Long Can a Polar Bear Hold Its Breath Underwater?

A polar bear’s longest recorded underwater dive lasted 3 minutes and 10 seconds. The bear covered an estimated 148–164 ft. (45 to 50 m) without surfacing during the dive, during which it was stalking seals.

How Fast Is a Polar Bear on Land?

A polar bear’s top speed on land is 40 mph (25 kph). It can only sustain this speed for short distances, however; its average walking speed is only about 3.4 mph (5.5 kph).
