IUCN/The World Conservation Union lists the marine, giant, southern river, and sea otters are listed as "endangered" (species has a very high risk of extinction). California’s southern sea otter has been listed as a threatened species under the Endangered Species Act since 1977. Populations in some areas are now thriving, and the recovery of the sea otter is considered one of the greatest successes in marine conservation.[1]. Their conservation legacy is truly remarkable. [18] One controversial hypothesis is that orcas have been eating the otters. Once containing more than half of the world’s sea otters, this population segment, which ranges from Kodiak Island through the western Aleutian Islands, has undergone an overall population decline of at least 55–67 percent since the mid-1980s. [5] The liver, kidneys, and lungs of sea otters also become damaged after they inhale oil or ingest it when grooming.[5]. By 1911, hunting for the animal's luxurious fur had reduced the sea otter population to fewer than 2000 individuals in the most remote and inaccessible parts of its range. Sea Otters . In the UK IOSF is the only charity solely dedicated to the conservation, protection and care of otters based on years of scientific research in the UK and around the world. [29] In April 2007, the Committee on the Status of Endangered Wildlife in Canada changed its assessment of the sea otter from "threatened" to "special concern". [11] The at the Olympic Coast National Marine Sanctuary is over 500. Modern efforts in sea otter conservation began in the early 20th century, when the sea otter was nearly extinct due to large-scale commercial hunting. Reintroductions of wild-caught sea otters to southeast Alaska, British Columbia, and Washington have been successful, although efforts to reintroduce California sea otters to the Channel Islands off the coast of Southern California were not as successful. The people of SeaWorld Parks & Entertainment are truly and deeply driven to inspire on behalf of, to celebrate and connect with, and to care for the natural world we all share. The International Otter Survival Fund (IOSF) is one of the world's leading otter charities. The sea otter matters, partly because it is unique, like any organism. Females are slightly smaller, weighing 14-33 kg and measuring 1-1.4 m in length. 1. CITES Appendix I lists species identified as endangered. Over 1,000 oiled sea otter carcasses were recovered,[21] with the actual number of deaths estimated to be several times that number. (Photo: N. Guujaaw/ Gwaii Haanas) The return of the sea otter Washington, now only stretches from Southern California to just north of Half Moon Bay,California. Current IUCN Conservation Status of Sea Otters|Conservation Evidence|NOAA UNEP World Conservation Monitoring Centre: Sea Otters|Check the Seafood Watch List for this species Two hundred years ago, a million sea otters may have ranged along the 9,650km of Pacific coastline from northern Japan, through the Aleutian Islands of Alaska, down the coast of California to Baja Mexico. The population decreased from between 150,000 and 300,000 individuals in the early 1700s to only 2,000 individuals in 1911. By 1911, hunting for the animal's luxurious fur had reduced the sea otter population to fewer than 2000 individuals in the most remote and inaccessible parts of its range. SeaWorld parks rescue and rehabilitate orphaned, ill, and injured otters. [30], 59 sea otters were translocated from Amchitka Island to Washington in 1969 and 1970, with annual surveys between 2000 and 2004 recording between 504 and 743 individuals. The committee's assessment reflects the ongoing strength of the B.C. Otters are well suited to a life on the water as they have webbed feet, dense fur to keep them warm, and can close their ears and nose when underwater. With up to one million hairs per square inch of skin, this species has the densest fur of any mammal . The conservation status of this ancient species has been a concern in the UK since they became close to extinction here after dramatic population declines from the mid 1950’s to the 1980’s. The otters then required a long rehabilitation period to regain the natural oils that protect their fur and to build up an insulating layer of air. [8] The state has listed the sea otter as an endangered species since 1981. Come face-to-face with the wonders of wildlife through species-focused episodes and related classroom activities. Enhydra lutris, also known by its common name of Sea Otters, are In this zone, only San Nicolas Island was designated as sea otter habitat, and sea otters found elsewhere in the area were supposed to be captured and relocated. As top predators, sea otters are critical to maintaining the balance of nearshore ecosystems, such as kelp forests, embayments and estuaries. Figure 5. More and more, however, the issues associated with sea otter conservation have merged into broader environmental concerns, such as ecosystem-wide changes in food sources and issues including climate change, ocean noise and coastal pollution.
