They’re members of the pinnipeds family that also includes fur seals and sea lions. Also, they prey on snakes, carrion, grass, and fruit. Like many other animals, sea otters find their safety in numbers. The sea otter is a marine mammal belonging to the weasel family of animals, specifically the Family Mustelidae. On land, coyotes and bobcats also predate on otters. But, did you know that sea otters have animals that prey on them too? Sea urchins beware! Approximately 40,000 of them are consumed annually in this area. Other than sea otters, eared seals also feed on krill (an animal that closely resembles a shrimp), lobsters, crabs, crustaceans such as shrimps, and fish, among others.eval(ez_write_tag([[336,280],'factsking_com-large-mobile-banner-1','ezslot_8',135,'0','0'])); White shark attacks are a leading cause of death among sea otters, especially in California. Other predators include sea lions in certain areas, as well as eagles, which eat otter pups. ( Log Out / Bald eagles get over 90 percent of their food from the ocean.eval(ez_write_tag([[300,250],'factsking_com-leader-1','ezslot_2',132,'0','0'])); Sea otters were once dominant in the coastal marine environments, not far from the islands. Change ), You are commenting using your Twitter account. Interestingly, the predators do not actually feed on the otters. Adults weigh up to 99 pounds and are the weasel family’s heaviest animals, but strangely the smallest of all marine mammals. This has led to a decline in sea otter numbers, especially in western Alaska. The sea otter’s predator depends on where the specific sea otter lives. Sea otters are known to carry rocks when they dive, to increase their weight when diving, as well as to crack open shells and protective armor, so they can eat the meat inside the shellfish. Today, they roam the American continent’s mountains and forests. Most Sea Otter "raft" in kelp beds with other otters. ( Log Out / Many farmers and ranchers regard them as destructive pests because they kill calves, lambs, and other livestock, as well as pets.eval(ez_write_tag([[250,250],'factsking_com-large-leaderboard-2','ezslot_7',131,'0','0'])); Bald eagles reside in their numbers along the Aleutian archipelago off the Alaskan coast. However, with the decline in sea otter populations, bald eagles have to turn to marine fish. Create a free website or blog at WordPress.com. There are several other predators that the Otter has to worry about as well. While feeding, Californian sea lions often cooperate with other species such as sea birds and dolphins.eval(ez_write_tag([[250,250],'factsking_com-leader-2','ezslot_10',133,'0','0'])); Killer whales have not always preyed on sea otters. Northern sea otters are found in the Aleutian Islands, Southern Alaska, British Columbia, and Washington. However, these whales find Otters to be a great meal. This increase has seen it compete for clams with the brown bear. It is only after biting the sea otters that white sharks realize their mistake. The sea otter ecosystem is largely made up of thick kelp forests. This notwithstanding, shark bites now account for over half of sea otter deaths. This decline has seen sea urchins increase in number because sea otters are their main predator. Those sea otters that live farther south, mostly hunt for a great white shark, and representatives of those sea otters that inhabit the more northern areas of the Pacific, hunt for killer whales. Their favorite prey has always been sea lions and seals. They place their nests on shoreline sea stacks, coastal cliffs, and islets. There are some predators of sea turtles as adults, but these marine reptiles are most vulnerable when in the egg and as hatchlings (small turtles recently emerged from the egg). In the U.S., there are two distinct sea otter subspecies, the Northern sea otter (Enhydra lutris kenyoni) and the Southern sea otter (Enhydra lutris nereis). Eared seals are recognized by their conspicuous ears and flippers. Sea otters inhabit the environments near shores where they dive to the floor of the sea to forage. They, therefore, kill otters so they can’t eat the fish and other sea creatures. The predators that Otters will encounter depend on where they happen to live. The only predator that they have to worry about is the killer whale. The sea otter’s diet includes about 40 marine species, including urchins, crabs, clams, abalones, mussels, and snails. Coyotes belong to the dog family, and once lived mainly in deserts and prairies. They found that the predators simply mistake otters for other more nutritious prey such as sea lions and seals. Sea otters have remarkable eating and foraging habits. Most sea lions aren’t picky eaters and feed a wide range of seafood. They can run at 40 miles an hour, making them exceptional hunters. Today, most people use traps for hunting them.eval(ez_write_tag([[300,250],'factsking_com-medrectangle-4','ezslot_1',128,'0','0'])); Some people hunt otters just for the thrill of killing them. If sea otters are not present , then urchin populations boom, which leads to overgrazing — killing all the kelp — and creating a wasteland known as an urchin barren . Humans also kill sea otters when they use fishing gear that traps the otter or hit the otter with boats. Although many of the bears are content with scavenging dead otters, some have, over the years, developed a taste for fresh otter meat.eval(ez_write_tag([[250,250],'factsking_com-large-mobile-banner-2','ezslot_9',134,'0','0'])); Eared seals, also referred to as otariids, are another predator of sea otters. These predators of sea urchins then proceed to crush their outer body with its powerful bit and sharp teeth. As others have written, killer whales and sharks are the biggest threat to sea otters of all sizes if they are in the ocean. Sea Otters live in the coastal waters of the Pacific Ocean in North American and Asia. The population of otters has been increasing ever since it was declared an endangered species and protected by the US. They have even managed to colonize cities such as Los Angeles and are found in most parts of North America. Sometimes, though, otters get caught fishermen’s nets.eval(ez_write_tag([[300,250],'factsking_com-box-4','ezslot_3',129,'0','0'])); One of the biggest predators of sea otters are coyotes. Sea otters eat about 25% of their weight every day, and is arguably the number one cause in sea otter deaths, when they cannot forage enough food… Sea urchins exploded in number after their predator, the Aleutian sea otter, became functionally extinct in the 1990's. Humans hunt sea otters for their meat and fur. As a result, the population of sea otters along the Californian coast has significantly decreased, raising concerns among conservationists.
