Sea Otter Habitat - Seattle Aquarium, USA

In the sea otter habitat at the Seattle Aquarium, on the city's waterfront, the otters float on their backs, roll in the water and groom almost nonstop. They spend hours a day at it, blowing air into their fur to keep it fluffy and waterproof.

Every otter here was rescued and can't return to the wild. One of them, Ruby, arrived in late 2025 as the aquarium's first southern sea otter.

At feeding time they crack open shellfish on their bellies. Now and then a northern fur seal appears instead, because the animals take turns in the habitat while it's being cleaned.

Did You Know? Sea otters have the thickest fur of any animal, with up to a million hairs per square inch. Unlike seals, they have no blubber, so that fur is what keeps them warm.
