Sea otters face many energetic and physiological challenges, such as high metabolic rates, heat loss, foraging demands and surface swimming behaviors, which they must overcome in order to survive. Although representing a challenge for adult sea otters, these problems are exacerbated in the youngest members of the population.

Behind its cute face and fluffy fur, the sea otter is an aquatic environmentalist. By munching on urchins, it helps kelp forests flourish, and by crunching on crabs, it promotes eelgrass in estuaries. But this marine mammal is endangered — and needs our help.

2022年8月26日 · A sea otter has two “swimming modes”, one when diving, and one when “cruising” on the water’s surface. When swimming on the surface, a sea otter usually swims belly-up on its back and can reach a speed of 0.9 mph with the help of its tail and its hindlimbs.

2015年2月16日 · Scuba diving underwater is akin to visiting another world, however what you’re able to see is largely dictated by factors such as visibility, time of year, geographic location and sometimes just plain luck. Although majority of sea otters are found in the Alaskan waters, you can also find them in parts of Japan, Russia, Canada and USA.

Sea otters can reach speeds of 1.5 kph (0.9 mph) on the surface and 9 kph (5.6 mph) under water. Diving. River otters can remain under water for 6 to 8 minutes. Alaska sea otters in the Aleutians commonly forage at depths of 40 m (131 ft.) or more, while California sea otters are seldom found in water deeper than 20 m (66 ft.).

2007年6月1日 · For wild otters (white bars), dive durations were recorded during 24-h observation periods to assess daily activity budgets as well as during focal foraging bouts. For captive otters (black bars), dive durations were recorded during forage diving in a water tower.

Sea otters are swift swimmers. Watch for them diving and surfacing with their prey. Sea otters are social animals and raft together in groups of a few dozen to hundreds of animals. Look for rafting groups! Though sea otters spend most of their lives at sea, they occasionally haul out on shore.

Sea otters spend a great deal of time floating on their backs at the surface. They move by paddling their hind limbs and sculling with their tails. For rapid swimming and for diving, they swim similarly to other otters, using up-and-down undulations of the body.

The sea otter can dive to depths ranging from 18 to 90 meters. This is an incredible accomplishment for such a small animal. Most mammals would be lucky to reach half that depth, but the sea otter can hold its breath for up to five minutes and swim at speeds of …

2023年8月18日 · Sea otters live along the rocky, tidal zones lining the Pacific coast of North America and dive for food within one to two kilometres offshore. They can dive to anywhere from 10 to 100 metres deep, using the kelp forests and reefs for hunting prey and for rest and shelter.
