Its prey ranges in size from tiny limpets and crabs to giant octopuses.

In California, they have been noted to ignore Pismo clams smaller than 3 inches (7 cm) across.
Where did the last sea otter live in Oregon?
The last native sea otter in Oregon was probably shot and killed in 1906. In 1970 and 1971, a total of 95 sea otters were transplanted from Amchitka Island, Alaska to the Southern Oregon coast. However, this translocation effort failed and otters soon again disappeared from the state. In 2004, a male sea otter took up residence at Simpson Reef off of Cape Arago for six months. This male is thought to have originated from a colony in Washington, but disappeared after a coastal storm. On 18 February 2009, a male sea otter was spotted in Depoe Bay off the Oregon Coast. It could have traveled to the state from either California or Washington. Two sea otters were observed about one mile north of the Winchuck River off the Southern Oregon coast on July 13, 2020.

Appearance
Habitat
- Sea otters prefer coastal habitats within a mile of the shoreline. They are frequently found in protected harbors, barrier reefs, and kelp forests that offer shelter from wind and waves. Most sea otters remain in habitats with rocky substrate, as their prey tend to be more plentiful in these areas.
Distribution
- The sea otters range spreads from Russia, across the North Pacific, and down to the Coast of California. Russia currently has the most stable population of sea otters, with over 25,000 animals remaining in slow, steady growth. This is believed to be about the same population volume the animals had prior to being hunted nearly to extinction.
Diet
- Sea otters will eat virtually anything they can get their little paws on. They are known to eat clams, mussels, crabs, octopus, sea urchins, snails, and fat innkeeper worms. They prey on crustaceans by using pairs of rocks to crush the outer shells, easily accessing the soft flesh inside. Sea otters are provided a varied diet while in human care. Because they are not exposed to predators, and …
Ecology
- Sea otters are what is known as a keystone species. This means that, when they are removed, the rest of the ecosystem collapses. Though there are many other interactions between sea otters and their prey species, the best example of this effect is the sea urchin. While there may not be immense numbers of sea otters, a single sea otter can eat a lot of sea urchins. If you removed al…
Conservation
- Historically, sea otters were hunted heavily for their fur coats. With protections in place, some populations have bounced back, while others have struggled. Sea otters have also been illegally killed because they directly compete with some fishery stocks. Sea otters have not been domesticated in any way. They have been kept successfully in zoos and aquariums, and becaus…
Effects
- In the abalone, crab, and clam fisheries, sea otter predation can cause fishermen to lose their livelihood. It should be noted, however, that shellfish declines have also been occurring in areas without sea otter predation. This indicates that outside factors, such as pollution, may be exacerbating the effects of the otters activities.
Conservation status
- It is highly illegal to own a sea otter. They are only kept in zoos and aquariums with special permits.
Miscellaneous
- Sea otters are also frequently trained using positive reinforcement techniques, making the otters easier to handle, and allowing them to voluntarily participate in medical check-ups, such as weighing and physical examinations.
Behavior
- Sea otters are social animals, and while they feed alone, they sleep in groups. Otter groups are called rafts, and the animals famously hold hands to keep from drifting apart. Males will also maintain territories, and breed with females who come to that territory searching for mates.
Breeding
- Males will mate with multiple females in a season, and breeding tends to be quite violent. The male will hold the female by her muzzle, frequently causing scars. Both breeding and birth occurs in the water.
