Sea otters can be found along the Pacific coasts of Asia and North America. These fun fuzzy creatures spend most of their time in the water, but on the rare occasion they’ll come ashore to take a nap.

Sea otters like to float on their backs and even eat their food off of their stomachs while they float. They are known to utilize rocks to break open shellfish to eat and to pry them off the ocean floor. (They also can dive up to 330 feet while they are scavenging for food!) Female sea otters care for their babies while floating on their backs—they nurse them on their chest and teach them to hunt and swim at a very young age.

In the past, the population of sea otters was close to a million. Unfortunately, due to the fur trade and other human activities, their population made a drastic drop to 1,000-2,000 at the beginning of the 20th century. Today, thanks to preservation efforts, that number has once again risen to over 100,000.

“As predators, sea otters are critical to maintaining the balance of the near-shore kelp ecosystems. Without sea otters, the undersea animals they prey on would devour the kelp forests off the coast that provide cover and food for many other marine animals.”

So next time you see a sea otter, give it it’s space but take the time to admire it! Sea otters are a threatened and important species to our ocean’s ecosystem.
