Other predators include sea lions in certain areas as well as eagles which eat otter pups. In the years after otters were hunted to near extinction now that a top predator was gone shellfish and sea urchins exploded in numbers up and down the coast.

Sea otters predator. Sea lions are a. Approximately that brutal. Sea otters are a keystone predator within the nearshore community but higher trophic level avian terrestrial and pelagic predators eg bald eagles brown bears wolves white sharks and killer whales prey on them.
For example some Indigenous communities and invertebrate fisheries in the North Pacific do not want the return of a keystone predator the sea otter because the otters eat the shellfish that these communities rely on for food. Otters are mainly nocturnal but occasionally venture out during the day. In addition the risk of oil spills remains an ongoing concern.
On land they have to be careful about coyotes. Otter predation is not common because few predators can catch an otter. However the IUCN still lists the sea otter as an endangered species and describes the significant threats to sea otters as oil pollution predation by orcas poaching and conflicts with fisheries sea otters can drown if entangled in fishing gear.
While sea otters are vulnerable to natural predators such as sharks the population also faces risks from other factors such as disease contaminants availability of prey and entanglement in commercial fishing gear. Otters are generally too swift and agile to be caught in the water but are able fighters if cornered on land. Because otters are such good predators the sea slugs that are typically eaten by crabs have the chance to do their job in removing excess algae from seagrass.
The study was conducted on the west coast of Vancouver Island in Canada and is representative of otter. One of the biggest predators of sea otters are coyotes. On the North Coast with sea otters long gone sunflower sea stars have been the major purple urchin predator.
There are several other predators that the Otter has to worry about as well. Some of them are on land while others will try to feed on them in the water. The study published June 11 in Science offers a new modeling framework to evaluate the significant long-term ecological changes driven by a top predator like the sea otter.
The sea otters predator depends on where the specific sea otter lives. In the Arctic killer whales often dine on sea otters while in the Californian coast great white sharks consume many otters each year. Sea otters are also considered an apex predator in their estuary habitat eating not only urchins but a variety of mollusks and crustaceansincluding crabs.
The virus known as the sea star wasting syndrome is on a par with horror movie scourges. The problem is we do not have a clear understanding of how recovering keystone predators affect local economies and human populations either positively or. This puts sea otters in direct competition with people who make a living from these shellfish.
On land coyotes and bobcats also predate on otters. It melts the limbs and bodies of what we used to call starfish including the many-armed sunflower sea star a purple urchin predator. Coyotes belong to the dog family and once lived mainly in deserts and prairies.
Using the tools of scientific research Hughes has discovered that sea otters the top predators in the food chain help keep the sea grass algae-free through their feeding habits which in turn allows the growth of a fish population and preserves a natural barrier to storms. If well-managed these economic benefits could offset commercial losses to shellfish fisheries of 7 million per year. After sea otters arrive in an area commercial fishers and coastal communities dependent on wild food harvest can face a transformed coastal landscape with shellfish populations decimated by sea otter foraging.
Females go to great lengths to protect their young. They have even managed to colonize cities such as Los Angeles and are found in most parts of North America. Harris cites another study that finds that about 11 percent of sea otters found dead on the California coast from 1998 to 2001 were killed at least in part by trauma.
Today they roam the American continents mountains and forests. Despite this impact on human harvesters sea otters often positively transform coastal. Eagles can be a problem too for the smaller Otters and the young.
Predators directly affect their prey as a source of mortality and prey respond by employing antipredator strategies.
