Scientific Name: Enhydra lutris

Category: mammal

Brief Description

A large marine mammal in the weasel family, often seen floating on its back in coastal waters.

Characteristics

Thick brown fur, small ears, large webbed hind feet, and a blunt snout. They have the densest fur of any animal and use their front paws for grooming and holding food.

Habitat

Nearshore coastal waters, typically in kelp forests or protected bays.

When to Find It

Can be observed year-round; most active during the day (diurnal).

Conservation Status

Endangered

Ecological Role

A keystone species that maintains the health of kelp forest ecosystems by controlling sea urchin populations.

Easily Confused With

River Otters, which are smaller, have longer tails, and swim belly-down; Harbor Seals, which lack the visible ears and thick fur look of an otter.

Observation Tips

Look for them in kelp beds using binoculars. Maintain a distance of at least 50 yards to avoid disturbing their rest or feeding behavior.

Interesting Facts

Sea otters don't have blubber; they rely on their incredibly thick fur and high metabolism to stay warm in cold water. They are one of the few mammals known to use tools, often using rocks to crack open shells.
