In fact, at 850,000 to 1 million hairs per square inch, sea otters have the thickest fur of any mammal. [73] The fluffy baby fur is replaced by adult fur after about 13 weeks. [96] "Yezo" refers to the island of Hokkaido in northern Japan. It has a long, stout body with a short broad head and snout with thick whiskers on the cheeks. The Southern sea otter (Enhydra lutris nereis) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. [184] The health of the kelp forest ecosystem is significant in nurturing populations of fish, including commercially important fish species. The majority of the southern sea otter’s teeth are flattened molars for crushing and chewing shelled, invertebrate prey. [98] By 2004, sea otters had repopulated all of their former habitat in these areas, with an estimated total population of about 27,000. The southern sea otter (Enhydra lutris nereis) is the heaviest member of the weasel family and the second smallest marine mammal. ", Archeological Research Issues for the Point Reyes National Seashore – Golden Gate National Recreation Area, "Sea Otter Show Striking Variability in Diets And Feeding Strategies", "U.S. [99] A massive decline in sea otter populations in the Aleutian Islands accounts for most of the change; the cause of this decline is not known, although orca predation is suspected. [183] Although human divers harvest red sea urchins both for food and to protect the kelp, sea otters hunt more sea urchin species and are more consistently effective in controlling these populations. [63] As autumn is the peak breeding season in most areas, males typically defend their territory only from spring to autumn. [29] The coloration of the pelage is usually deep brown with silver-gray speckles, but it can range from yellowish or grayish brown to almost black. Endangered Species Act and “depleted” under the U.S. Marine Mammal Protection Act of 1977. Sea otter’s body is covered in a dense fur that constantly must be groomed to maintain its insulating properties and cleanliness; therefore, a sea otter will spend up to 10% of its time grooming. [104] The sea otter population in Prince William Sound was also hit hard by the Exxon Valdez oil spill, which killed thousands of sea otters in 1989. [190] The beginning of commercial exploitation had a great impact on the human, as well as animal, populations  the Ainu and Aleuts have been displaced or their numbers are dwindling, while the coastal tribes of North America, where the otter is in any case greatly depleted, no longer rely as intimately on sea mammals for survival. Known for their agility and playful social behavior, our dolphins are a must-see at Georgia Aquarium! [132] Recently, a toxin called microcystin, produced by a type of cyanobacteria (Microcystis), seems to be concentrated in the shellfish the otters eat, poisoning them. M O L L U S K S. Habitat: Coasts of the Northern & Eastern … [165] In 1812, the Russians founded an agricultural settlement at what is now Fort Ross in northern California, as their southern headquarters. [60] The Aleuts carved sea otter bones for use as ornaments and in games, and used powdered sea otter baculum as a medicine for fever. [71] Twins occur in 2% of births; however, usually only one pup survives. Southern sea otters can live to approximately 15 years for males and 16 years for females. “There is so much more to a sea otter than meets the eye. It preys mostly on marine invertebrates such as sea urchins, various molluscs and crustaceans, and some species of fish. [88] Similarly, forced copulation by sea otters involving animals other than Pacific harbor seals has occasionally been reported. Southern sea otters off Central California prey largely on invertebrates, such as urchins, crabs, abalone, and clams. Of these, about 19,000 are at the Kurils, 2,000 to 3,500 at Kamchatka and another 5,000 to 5,500 at the Commander Islands. This number still keeps them on track for removal from the endangered species list, although just barely. The lighter-colored otter in the video is Nyac, a survivor of the 1989 Exxon Valdez oil spill. [127] However, after engaging in a period of public commentary in 2005, the Fish and Wildlife Service failed to release a formal decision on the issue. Behind its cute face and fluffy fur, the sea otter is an aquatic environmentalist. Their habitats also need the root systems of mature trees, as well as fallen tree debris. This pouch also holds a rock, unique to the otter, that is used to break open shellfish and clams. Urban runoff transporting cat feces into the ocean brings Toxoplasma gondii, an obligate parasite of felids, which has killed sea otters. Loss of the habitat and nutrients provided by kelp forests leads to profound cascade effects on the marine ecosystem. [56] There, the sea otter eats while floating on its back, using its forepaws to tear food apart and bring it to its mouth. During the nineteenth century, the southern sea otter was known along the entire Pacific coast of North America, from Alaska to central Baja California. However, biologists have confirmed isolated sightings of sea otters in these areas since the mid-1990s. [145] The fish species were usually bottom-dwelling and sedentary or sluggish forms, such as Hemilepidotus hemilepidotus and family Tetraodontidae. [192], Sea otters can do well in captivity, and are featured in over 40 public aquariums and zoos. [118] By 1817, sea otters in the area were practically eliminated and the Russians sought permission from the Spanish and the Mexican governments to hunt further and further south of San Francisco. These are the first documented sightings of otters this far south in 30 years. Southern sea otter belongs to family Mustelidae, the same as weasels and wolverines. Southern sea otter consumes many types of prey including sea urchins, snails, clams, abalone, mussels, crabs, scallops, fish, barnacles, octopus, worms, and squid, which it captures with its clawed paws, not its jaws. [24], Although each adult and independent juvenile forages alone, sea otters tend to rest together in single-sex groups called rafts. The extinct sea mink of northeastern North America is another mustelid that had adapted to a marine environment. It could have traveled to the state from either California or Washington. Sea otter pelts were given in potlatches to mark coming-of-age ceremonies, weddings, and funerals. [109] In 2004, a male sea otter took up residence at Simpson Reef off of Cape Arago for six months. [116][117] Historical records revealed the Russian-American Company sneaked Aleuts into San Francisco Bay multiple times, despite the Spanish capturing or shooting them while hunting sea otters in the estuaries of San Jose, San Mateo, San Bruno and around Angel Island. Currently, the most stable and secure part of the sea otter's range is Russia. [95], The sea otter population is thought to have once been 150,000 to 300,000,[19] stretching in an arc across the North Pacific from northern Japan to the central Baja California Peninsula in Mexico. Males usually raft together during non-breeding season. The southern sea otter lives in shallower waters off the rocky Pacific coasts, staying inside and very close to large kelp beds, which provide protection and support large numbers of shellfish. [31] The hind feet, which provide most of its propulsion in swimming, are long, broadly flattened, and fully webbed. Initially, the objects it retrieves are of little food value, such as brightly colored starfish and pebbles. The southern river otter can be found in marine, freshwater, and terrestrial habitats, but are mostly found in freshwater lakes and rivers having a significant amount of dense vegetation, especially along the shorelines, which must be present to use as cover. [139], Historian Adele Ogden described sea otters are particularly abundant in "Lower California", now the Baja California Peninsula, where "seven bays...were main centers". Rodents (of which the beaver is one) are not closely related to otters, which are carnivorans. Southern Sea Otter Webcam; Ocean Voyager Webcam; Underwater Puffin Webcam; Piranha Webcam; African Penguin Webcam; About Cold Water Quest. Predators of sea otters include sharks and killer whales. Bald eagles have … (1.8-2.3 kg). It can chew and swallow small mussels with their shells, whereas large mussel shells may be twisted apart. [13] According to the U.S. Geological Survey and the CDC, northern sea otters off Washington have been infected with the H1N1 flu virus and "may be a newly identified animal host of influenza viruses". [24] For its size, the male otter's baculum is very large, massive and bent upwards, measuring 150 mm (5.9 in) in length and 15 mm (0.59 in) at the base. Along the coasts of what is now Mexico and California, Spanish explorers bought sea otter pelts from Native Americans and sold them in Asia. IUCN Red List: Endangered. Consequently, sexually mature females can be distinguished by bloody or scarred nose regions. [61] The largest raft ever seen contained over 2000 sea otters. [176][177] Although disease has clearly contributed to the deaths of many of California's sea otters, it is not known why the California population is apparently more affected by disease than populations in other areas. The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Enhydra lutris nereis is listed on Appendix I of CITES. [124] The spring 2016 count at San Nicolas Island was 104 sea otters, continuing a 5-year positive trend of over 12% per year. Rarely ventures onto land. Although it can hold its breath for up to five minutes,[31] its dives typically last about one minute and not more than four. Choose from high quality, high res, hd, widescreen, and other options. [163], Russian hunting expanded to the south, initiated by American ship captains, who subcontracted Russian supervisors and Aleut hunters[164] in what are now Washington, Oregon, and California. Today, southern sea otters live along the central coast of California; northern sea otters live along the coasts of Washington, Canada, and Alaska. [166] When Russia sold Alaska to the United States in 1867, the Alaska population had recovered to over 100,000, but Americans resumed hunting and quickly extirpated the sea otter again. Reduced range and population size, vulnerability to oil spills, and oil spill risk from coastal tanker traffic were the primary reasons for listing. [33], Long, highly sensitive whiskers and front paws help the sea otter find prey by touch when waters are dark or murky. Cold water is kept completely away from the skin and heat loss is limited. [5] Male sea otters usually weigh 22 to 45 kg (49 to 99 lb) and are 1.2 to 1.5 m (3 ft 11 in to 4 ft 11 in) in length, though specimens up to 54 kg (119 lb) have been recorded. [170] Poaching was a serious concern in the Russian Far East immediately after the collapse of the Soviet Union in 1991; however, it has declined significantly with stricter law enforcement and better economic conditions.[102]. [2] A subsequent international ban on hunting, sea otter conservation efforts, and reintroduction programs into previously populated areas have contributed to numbers rebounding, and the species occupies about two-thirds of its former range. [16][49][55] Prevention of oil spills and preparation to rescue otters if one happens is a major focus for conservation efforts. United States, otter origins, however one otter had a haplotype not previously reported, and could represent a remnant of the original native Mexican otter population. Many Aleuts were either murdered by the Russians or died from diseases the hunters had introduced. [55] The sea otter may also pluck snails and other organisms from kelp and dig deep into underwater mud for clams. [129], Although the southern sea otter's range has continuously expanded from the remnant population of about 50 individuals in Big Sur since protection in 1911, from 2007 to 2010, the otter population and its range contracted and since 2010 has made little progress. This aquatic member of the weasel family is found along the coasts of the Pacific Ocean in North America and Asia. 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. It uses rocks, shells and other hard materials from the ocean floor as shell-crushing tools, while balancing its prey on its chest and stomach. There are only about 3,000 southern sea otters left in the wild today. 1 Stats. [69] Gestation appears to vary from four to twelve months, as the species is capable of delayed implantation followed by four months of pregnancy. [163] When Cook's ship later stopped at a Chinese port, the pelts rapidly sold at high prices, and were soon known as "soft gold". The Southern Sea Otter is a type of mammal Friend that debuted in the original Kemono Friends mobile game. [140] However, male and female otters have been confirmed by scientists off shores of the Baja Peninsula in a 2014 study, who hypothesize that otter dispersed there beginning in 2005. [72] Mothers have been observed to lick and fluff a newborn for hours; after grooming, the pup's fur retains so much air, the pup floats like a cork and cannot dive. [175] Necropsies of dead sea otters indicate diseases, particularly Toxoplasma gondii and acanthocephalan parasite infections, are major causes of sea otter mortality in California. Trophic Level:Omnivore. It ranges from two to three months in southern sea otters and can last as long as eight months in northern sea otters. [126], When the USFWS implemented the translocation program, it also attempted, in 1986, to implement "zonal management" of the Californian population. [193] The Seattle Aquarium became the first institution to raise sea otters from conception to adulthood with the birth of Tichuk in 1979, followed by three more pups in the early 1980s. [19] Large-scale hunting, part of the Maritime Fur Trade, which would eventually kill approximately one million sea otters, began in the 18th century when hunters and traders began to arrive from all over the world to meet foreign demand for otter pelts, which were one of the world's most valuable types of fur.[19]. [16], The small geographic ranges of the sea otter populations in California, Washington, and British Columbia mean a single major spill could be catastrophic for that state or province. Jump in on a wide variety of experiences and events that will make your trip to Georgia Aquarium even more memorable. The southern subspecies lives along the central California coast from San Mateo County to Santa Barbara County. Sea otters currently have stable populations in parts of the Russian east coast, Alaska, British Columbia, Washington, and California, with reports of recolonizations in Mexico and Japan. [92] Although they are most strongly associated with rocky substrates, sea otters can also live in areas where the sea floor consists primarily of mud, sand, or silt. The pattern of disappearances is consistent with a rise in predation, but there has been no direct evidence of orcas preying on sea otters to any significant extent. Although it can walk on land, the sea otter is capable of living exclusively in the ocean. [62], A male sea otter is most likely to mate if he maintains a breeding territory in an area that is also favored by females. This, of course, would be the adorable and charismatic sea otter, or more specifically, the southern sea otter. Versions of a widespread Aleut legend tell of lovers or despairing women who plunge into the sea and become otters. [30] In adults, the head, throat, and chest are lighter in color than the rest of the body. [93] Their northern range is limited by ice, as sea otters can survive amidst drift ice but not land-fast ice. The male lives to about 10 to 15 years in the ocean, while the female’s lifespan can be a little longer. There was some contraction from the northern (now Pigeon Point) and southern limits of the sea otter's range during the end of this period, circumstantially related to an increase in lethal shark bites, raising concerns that the population had reached a plateau. For these reasons, the sea otter remains classified as an endangered species. Studies on southern sea otters in California have shown that diet can be a highly individual thing, in which an otter will specialize in one to three types of prey that is not influenced directly by prey availability. Cyanobacteria are found in stagnant freshwater enriched with nitrogen and phosphorus from septic tank and agricultural fertilizer runoff, and may be flushed into the ocean when streamflows are high in the rainy season. [160] In 1778, British explorer Captain James Cook reached Vancouver Island and bought sea otter furs from the First Nations people. [87], There are several documented cases in which male sea otters have forcibly copulated with juvenile harbor seals, sometimes resulting in death. Hunting records researched by historian Adele Ogden place the westernmost limit of the hunting grounds off the northern Japanese island of Hokkaido and the easternmost limit off Punta Morro Hermosa about 21.5 miles (34.6 km) south of Punta Eugenia, Baja California's westernmost headland in Mexico. North Pacific areas that do not have sea otters often turn into urchin barrens, with abundant sea urchins and no kelp forest. Three subspecies of the sea otter are recognized with distinct geographical distributions. [47] [7], Fossil evidence indicates the Enhydra lineage became isolated in the North Pacific approximately 2 million years ago, giving rise to the now-extinct Enhydra macrodonta and the modern sea otter, Enhydra lutris. [183], Left: Aleut sea otter amulet in the form of a mother with pup. [59] To open hard shells, it may pound its prey with both paws against a rock on its chest. These sea otter may have dispersed from San Nicolas Island, which is 300 kilometres (190 mi) away, as individuals have been recorded traversing distances of over 800 kilometres (500 mi). [43], An adult's 32 teeth, particularly the molars, are flattened and rounded for crushing rather than cutting food. This otter can dive to 300 feet in search of food. Hearing, smell, touch and sight are very well developed in the sea otter and are important in hunting as well as in detecting danger. Sea otters play a vital role in the health and stability of the nearshore marine ecosystem as a keystone species; Sea otter fur is the densest of any mammal at about 1 million hairs per square inch (We have 100,000 hairs on our entire head). [85] Several captive individuals have lived past 20 years, and a female at the Seattle Aquarium died at the age of 28 years. This one is sixteen minutes of one southern sea otter showing rarely seen otter behaviors such as feeding specialization; hierarchical prey selection; use of search images; dive lengths and surface intervals; the use of tools and tactile and oral sensory systems used in foraging and feeding in intertidal areas in the Moss Landing Wildlife Area on February 12, 2020. The Alaskan subspecies have predators on land such as coyotes or brown bears. [66] Distressed or frightened adults may whistle, hiss, or in extreme circumstances, scream. [157] The surviving crew members, which included naturalist Georg Steller, discovered sea otters on the beaches of the island and spent the winter hunting sea otters and gambling with otter pelts. [115], Sea otters were once numerous in San Francisco Bay. Historically, Sea Otters occurred across the North Pacific Rim, ranging from Hokkaido, Japan, through the Kuril Islands, the Kamchatka Peninsula, the Commander Islands, the Aleutian Islands, peninsular and south coastal Alaska and south to Baja California, Mexico (Kenyon 1969). Hatch, David R. (2002) Elakha: Sea Otters, Native People, and European Colonization in the North Pacific. [161] By the 1760s, the Russians had reached Alaska. Surprisingly, though, the diets of individuals were more specialized in these areas than in areas where food was plentiful. The southern sea otter is dark to reddish brown in color with a lighter colored head, throat, and chest. [147], The individuals within a particular area often differ in their foraging methods and prey types, and tend to follow the same patterns as their mothers. [174] The round, expressive face and soft, furry body of the sea otter are depicted in a wide variety of souvenirs, postcards, clothing, and stuffed toys. Considered "cute" by many, sea otters are actually feisty by nature. The southern sea otter is dark to reddish brown in color with a lighter colored head, throat, and chest. They use their long, flat … [58] In California, great white sharks are their primary predator[154] but there is no evidence that the sharks eat them. [98], Alaska is the heartland of the sea otter's range. Its relatively large kidneys enable it to derive fresh water from sea water and excrete concentrated urine. Adele Ogden wrote in "The California Sea Otter Trade" that sea otter were hunted "from Yezo northeastward past the Kuril Group and Kamchatka to the Aleutian Chain". [156], Sea otters have the thickest fur of any mammal, which makes them a common target for many hunters. [125] If populations continued to grow and ESA delisting occurred, southern sea otters would still be fully protected by state regulations and the Marine Mammal Protection Act, which set higher thresholds for protection, at approximately 8,400 individuals. [153] The role of sea otters in maintaining kelp forests has been observed to be more important in areas of open coast than in more protected bays and estuaries. It must eat 20% to 25% of its body weight every day to maintain normal body temperature, so it will spend much of the day foraging. The cry of a pup is often compared to that of a gull. 2006b). Leading mammalian predators of this species include orcas and sea lions, and bald eagles may grab pups from the surface of the water. Enhydra lutris lutris (nominate), the Asian sea otter, ranges from the Kuril Islands north of Japan to Russia's Commander Islands in the western Pacific Ocean. Southern sea otters have been killed illegally because of the belief that they compete with commercial fishers and divers collecting sea urchins commercially. [83] Mothers have been known to carry their pups for days after the pups' deaths. [142] In most of its range, the sea otter's diet consists almost exclusively of marine benthic invertebrates, including sea urchins, fat innkeeper worms, a variety of bivalves such as clams and mussels, abalone, other mollusks, crustaceans, and snails. A major Ainu epic, the Kutune Shirka, tells the tale of wars and struggles over a golden sea otter. The tail is short in comparison to those of other otters. [12] The full genome of the northern sea otter (Enhydra lutris kenyoni) was sequenced in 2017 and may allow for examination of the sea otter's evolutionary divergence from terrestrial mustelids. [102] Before the 19th century, around 20,000 to 25,000 sea otters lived near the Kuril Islands, with more near Kamchatka and the Commander Islands. [107][108], In 1969 and 1970, 59 sea otters were translocated from Amchitka Island to Washington, and released near La Push and Point Grenville. Download a beautiful Southern sea otters wallpaper from the Monterey Bay Aquarium. [48][49] Its digestive efficiency is estimated at 80 to 85%,[50] and food is digested and passed in as little as three hours. [89], Sea otters live in coastal waters 15 to 23 metres (50 to 75 ft) deep,[90] and usually stay within a kilometre (⅔ mi) of the shore. As members of the weasel or mustelid family, southern sea otters are the smallest marine mammal. A newborn southern sea otter pup is a buff color, 22 to 24 inches (55 – 60 cm) in length and 4 to 5 lbs. This allows space for competing species and increases species diversity.[153]. [96], In about two-thirds of its former range, the species is at varying levels of recovery, with high population densities in some areas and threatened populations in others. [61] Adult females move freely between male territories, where they outnumber adult males by an average of five to one. The Nuu-chah-nulth, Haida, and other First Nations of coastal British Columbia used the warm and luxurious pelts as chiefs' regalia. [130] In response to recovery efforts, the population climbed steadily from the mid-20th century through the early 2000s, then remained relatively flat from 2005 to 2014 at just under 3,000. They can swim as close as six feet off shore along the Olympic coast. [187], Among the Ainu, the otter is portrayed as an occasional messenger between humans and the creator. ©2021 Georgia Aquarium 225 Baker Street Northwest, Atlanta, GA. Georgia Aquarium is a nonprofit committed to inspiring awareness and preservation of our ocean and aquatic animals worldwide. It had stopped in the Aleutian Islands, by 1808, as a conservation measure imposed by the Russian-American Company. It is unique among the mustelids in not making dens or burrows, in having no functional anal scent glands, and in being able to live its entire life without leaving the water. [188] The sea otter is a recurring figure in Ainu folklore. Today's population of California sea otters are the descendants of a single colony of about 50 sea otters located near Bixby Creek Bridge in March 1938 by Howard G. Sharpe, owner of the nearby Rainbow Lodge on Bixby Bridge in Big Sur. This results in a higher female to male ratio in adults.
