[197] Milo, the darker one, died of lymphoma in January 2012[198], species of marine mammal from the northern and eastern coasts of the North Pacific Ocean, At least one female is known to have died from an infected nose. Potential current threats to this protected subspecies include entanglement in fishing nets, oil spills and predation by the great white shark. [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. He brings more than 30 years of professional marine mammal management, husbandry, rehabilitation, and training experience to the Aquarium. [63] As autumn is the peak breeding season in most areas, males typically defend their territory only from spring to autumn. [181], The debate is complicated because sea otters have sometimes been held responsible for declines of shellfish stocks that were more likely caused by overfishing, disease, pollution, and seismic activity. [120], In the late 1980s, the USFWS relocated about 140 southern sea otters to San Nicolas Island in southern California, in the hope of establishing a reserve population should the mainland be struck by an oil spill. [26] With up to 150,000 strands of hair per square centimetre (nearly one million per sq in), its fur is the densest of any animal. 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. 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). [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. [51], The sea otter is diurnal. [161] By the 1760s, the Russians had reached Alaska. The tail is short in comparison to those of other otters. [56] Juveniles are typically independent at six to eight months, but a mother may be forced to abandon a pup if she cannot find enough food for it;[77] at the other extreme, a pup may nurse until it is almost adult size. Surprisingly, though, the diets of individuals were more specialized in these areas than in areas where food was plentiful. First, its use of rocks to dislodge prey and to open shells makes it one of the few mammal species to use tools. Adult males are highly territorial during breeding season and will not permit other males to enter their territory. Like other members of this family, they have very thick fur.

If you continue to use this site, you consent to our use of cookies. As word spread, people from all over Europe and North America began to arrive in the Pacific Northwest to trade for sea otter furs. 2006b). [105] In 2008, Canada determined the status of sea otters to be "special concern". [63] During this time, males patrol the boundaries of their territories to exclude other males,[63] although actual fighting is rare. [150] A 2007 Californian study demonstrated, in areas where food was relatively scarce, a wider variety of prey was consumed. “There is so much more to a sea otter than meets the eye. [158] In 1775 at Okhotsk, sea otter pelts were worth 50–80 rubles as opposed to 2.5 rubles for sable. [26] Most of its need for water is met through food, although, in contrast to most other marine mammals, it also drinks seawater. [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. They swim belly-up, moving through the water at 3-5 miles an hour with their webbed hind feet. The southern sea otter is the smallest marine mammal in North America at up to 4 feet (1.2 m) long and up to 50 pounds (23 kg) for females and 70 pounds (32 kg) for males. [55] It is the only marine mammal that catches fish with its forepaws rather than with its teeth. [16], The last native sea otter in Oregon was probably shot and killed in 1906. Southern Sea Otter Festival Pavilion KF3 Nexon Game: For voice lines, see Southern Sea Otter/KF3/Voice. 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. Sea otter is found along coastal areas of the northern Pacific Ocean and the southern Bering Sea. Leading mammalian predators of this species include orcas and sea lions, and bald eagles may grab pups from the surface of the water. In California, great white sharks are their primary predator[154] but there is no evidence that the sharks eat them. North Pacific areas that do not have sea otters often turn into urchin barrens, with abundant sea urchins and no kelp forest. ", 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. Wild sea otters typically have a lifespan between 15 and 20 years. Sea urchins graze on the lower stems of kelp, causing the kelp to drift away and die. Russian fur-hunting expeditions soon depleted the sea otter populations in the Commander Islands, and by 1745, they began to move on to the Aleutian Islands. Read about how we use cookies by visiting our "Privacy and Terms." It is unique among the mustelids in not making dens or burrows, in having no functional anal scent glands,[4] and in being able to live its entire life without leaving the water. [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]. [142][143] Its prey ranges in size from tiny limpets and crabs to giant octopuses. Female sea otter is pregnant for four-and-a-half months. [44] Seals and sea otters are the only carnivores with two pairs of lower incisor teeth rather than three;[45] the adult dental formula is 3.1.3.12.1.3.2. M O L L U S K S. Habitat: Coasts of the Northern & Eastern … The Russians found the sea otter far more valuable than the sable skins that had driven and paid for most of their expansion across Siberia. (. The life of a southern sea otter. Under Aleksandr I, the administration of the merchant-controlled company was transferred to the Imperial Navy, largely due to the alarming reports by naval officers of native abuse; in 1818, the indigenous peoples of Alaska were granted civil rights equivalent to a townsman status in the Russian Empire. Southern sea otters (Enhydra lutris nereis), also known as California sea otters, were listed as threatened in 1977 under the Endangered Species Act. (29.5 kg) and adult females average 45 lbs. [57] It uses its lower incisor teeth to access the meat in shellfish. The sea otter has a metabolic rate two or three times that of comparatively sized terrestrial mammals. [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. [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. [16] Sea otters can thoroughly remove abalone from an area except for specimens in deep rock crevices,[149] however, they never completely wipe out a prey species from an area. [112][113][114] Their principal range has gradually expanded and extends from Pigeon Point in San Mateo County to Santa Barbara County. Webbed hind feet that can be spread wide like flippers are well adapted for swimming. [119] Remnant sea otter populations may have survived in the bay until 1840, when the Rancho Punta de Quentin was granted to Captain John B. R. Cooper, a sea captain from Boston, by Mexican Governor Juan Bautista Alvarado along with a license to hunt sea otters, reportedly then prevalent at the mouth of Corte Madera Creek. Versions of a widespread Aleut legend tell of lovers or despairing women who plunge into the sea and become otters. [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. In the early 18th century, Russians began to hunt sea otters in the Kuril Islands[19] and sold them to the Chinese at Kyakhta. The extinct sea mink of northeastern North America is another mustelid that had adapted to a marine environment. Fish and Wildlife Service (USFWS) determined that the population should exceed 3,090 for three consecutive years. [3] When underwater, its body is long and streamlined, with the short forelimbs pressed closely against the chest. Three subspecies of the sea otter are recognized with distinct geographical distributions. [141], Sea otters consume over 100 prey species. [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. [84] A captive male sired offspring at age 19. This population increased to over 5,600 in 2013 with an estimated annual growth rate of 7.2%, and their range on the island's west coast extended north to Cape Scott and across the Queen Charlotte Strait to the Broughton Archipelago and south to Clayoquot Sound and Tofino.

To keep from drifting out to sea when resting and eating, sea otters may wrap themselves in kelp. [65] Females coo when they are apparently content; males may grunt instead. Sea otters are without a doubt the most popular animal here at the slough. [182] Although many factors affect shellfish stocks, sea otter predation can deplete a fishery to the point where it is no longer commercially viable. 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. Russia was also exploring the far northern Pacific at this time, and sent Vitus Bering to map the Arctic coast and find routes from Siberia to North America. [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. [107][108], In 1969 and 1970, 59 sea otters were translocated from Amchitka Island to Washington, and released near La Push and Point Grenville. [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. [55][182] Shellfish declines have also occurred in many parts of the North American Pacific coast that do not have sea otters, and conservationists sometimes note the existence of large concentrations of shellfish on the coast is a recent development resulting from the fur trade's near-extirpation of the sea otter. JAYASRI GM, 2 days ago 0 6 min read 7 . [56] There, the sea otter eats while floating on its back, using its forepaws to tear food apart and bring it to its mouth. [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. She has since been redesigned and has appeared in the mobile games Kemono Friends Festival, Kemono Friends 3, and Kemono Friends Pavilion. [55] Mating takes place in the water and can be rough, the male biting the female on the muzzle – which often leaves scars on the nose – and sometimes holding her head under water. [31] The hind feet, which provide most of its propulsion in swimming, are long, broadly flattened, and fully webbed. [145] The fish species were usually bottom-dwelling and sedentary or sluggish forms, such as Hemilepidotus hemilepidotus and family Tetraodontidae. [24], Although each adult and independent juvenile forages alone, sea otters tend to rest together in single-sex groups called rafts. Both items are on display at the Peter the Great Museum of Anthropology and Ethnography in St. Petersburg. [13], The first scientific description of the sea otter is contained in the field notes of Georg Steller from 1751, and the species was described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. Bald eagles have … Distribution. The sea otter walks with a clumsy, rolling gait on land, and can run in a bounding motion. California’s southern sea otter has been listed as a threatened species under the Endangered Species Act since 1977. [33] The tail is fairly short, thick, slightly flattened, and muscular. Behind its cute face and fluffy fur, the sea otter is an aquatic environmentalist. Delayed implantation periods in sea otters depend on individual and geographic variation. Northern sea otters possess longer mandibles (lower jaws) while southern sea otters have longer rostrums and smaller teeth. [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. [42] Its hearing is neither particularly acute nor poor. In the 1980s, the area was home to an estimated 55,000 to 100,000 sea otters, but the population fell to around 6,000 animals by 2000. [94] Individuals generally occupy a home range a few kilometres long, and remain there year-round. If the sea otter pelts brought back by Bering's survivors had been sold at Kyakhta prices they would have paid for one tenth the cost of Bering's expedition. [136], For southern sea otters to be considered for removal from threatened species listing, the U.S. Dive into the world of dolphins during our awe-inspiring and educational dolphin presentation. However, most individuals will take advantage of seasonally abundant swells in prey species, such as squid and red crab. [167] Prices rose as the species became rare. They eat, rest, groom themselves, and breed in the water. During the mating season, the male bites the snout of the female in a display of courting behavior. The fur of the sea otter is the densest of all mammals at about 350,000 to 1,000,000 hairs per square inch, compared to dogs that only have 1,000 to 60,000 hairs per square inch. Uses its nose and whiskers to help locate prey and to detect vibrations under the water. [174] Unusually high mortality rates amongst adult and subadult otters, particularly females, have been reported. [34] The bones show osteosclerosis, increasing their density to reduce buoyancy. Since I was born in Monterey, California I never knew a world without sea otters around. Southern sea otter has a high metabolic rate that is about 2.5 times greater than that of terrestrial animals. [63] Males that do not have territories tend to congregate in large, male-only groups,[63] and swim through female areas when searching for a mate. The southern sea otter, Enhydra lutris nereis, continues its climb toward recovery, according to the annual count released today by the U.S. Geological Survey and partners. [11] In some respects, though, the sea otter is more fully adapted to water than pinnipeds, which must haul out on land or ice to give birth. Urban runoff transporting cat feces into the ocean brings Toxoplasma gondii, an obligate parasite of felids, which has killed sea otters. 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. [135] Great white sharks do not consume relatively fat-poor sea otters but shark-bitten carcasses have increased from 8% in the 1980s to 15% in the 1990s and to 30% in 2010 and 2011. 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. Its diet includes prey species that are also valued by humans as food, leading to conflicts between sea otters and fisheries. The Southern Sea Otter is a type of mammal Friend that debuted in the original Kemono Friends mobile game. [24] The fur is thick year-round, as it is shed and replaced gradually rather than in a distinct molting season. Diet: Sea Urchins, Mollusks, Crustaceans and some species of fish . Otter were also taken from San Benito Island, Cedros Island, and Isla Natividad in the Bay. In these cultures, many of which have strongly animist traditions full of legends and stories in which many aspects of the natural world are associated with spirits, the sea otter was considered particularly kin to humans. [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. In 1799, Emperor Paul I consolidated the rival fur-hunting companies into the Russian-American Company, granting it an imperial charter and protection, and a monopoly over trade rights and territorial acquisition. [6] Genetic analysis indicates the sea otter and its closest extant relatives, which include the African speckle-throated otter, European otter, African clawless otter and oriental small-clawed otter, shared an ancestor approximately 5 million years ago. [124] The spring 2016 count at San Nicolas Island was 104 sea otters, continuing a 5-year positive trend of over 12% per year. [71] In 1911, Russia, Japan, Great Britain (for Canada) and the United States signed the Treaty for the Preservation and Protection of Fur Seals, imposing a moratorium on the harvesting of sea otters. [126], When the USFWS implemented the translocation program, it also attempted, in 1986, to implement "zonal management" of the Californian population. [157] Thus began what is sometimes called the "Great Hunt", which would continue for another hundred years. Southern sea otters have been killed illegally because of the belief that they compete with commercial fishers and divers collecting sea urchins commercially. Scientific Name: Enhydra Lutris. [110] On 18 February 2009, a male sea otter was spotted in Depoe Bay off the Oregon Coast. [25], Unlike most other marine mammals, the sea otter has no blubber and relies on its exceptionally thick fur to keep warm. Sea otters spend most of their time near the shore. Consequently, sexually mature females can be distinguished by bloody or scarred nose regions. Its range extended across the Aleutians to the Siberian … [30] In adults, the head, throat, and chest are lighter in color than the rest of the body. [71] In the wild, sea otters live to a maximum age of 23 years,[24] with lifespans ranging from 10 to 15 years for males and 15–20 years for females. One animal I run into on a daily basis is one I used to take for granted. Today, southern sea otters live along the central coast of California; northern sea otters live along the coasts of Washington, Canada, and Alaska. Sea otters spend a majority of their day eating, sleeping, and grooming. In this pouch (preferentially the left one), the animal stores collected food to bring to the surface. [28] As the ability of the guard hairs to repel water depends on utmost cleanliness, the sea otter has the ability to reach and groom the fur on any part of its body, taking advantage of its loose skin and an unusually supple skeleton. Archaeological evidence indicates that for thousands of years, indigenous peoples have hunted sea otters for food and fur. In 1970 and 1971, a total of 95 sea otters were transplanted from Amchitka Island, Alaska to the Southern Oregon coast. [104], Another area of concern is California, where recovery began to fluctuate or decline in the late 1990s. Sea otters may help mitigate effects of climate change by their cascading trophic influence[151], Reintroduction of sea otters to British Columbia has led to a dramatic improvement in the health of coastal ecosystems,[152] and similar changes have been observed as sea otter populations recovered in the Aleutian and Commander Islands and the Big Sur coast of California[153] However, some kelp forest ecosystems in California have also thrived without sea otters, with sea urchin populations apparently controlled by other factors. [188] The sea otter is a recurring figure in Ainu folklore. [75] The milk from a sea otter's two abdominal nipples is rich in fat and more similar to the milk of other marine mammals than to that of other mustelids. As of 2017, the population was estimated at over 2,000 individuals, and their range extends from Point Grenville in the south to Cape Flattery in the north and east to Pillar Point along the Strait of Juan de Fuca. [77] Pups born to experienced mothers have the highest survival rates. The majority of the southern sea otter’s teeth are flattened molars for crushing and chewing shelled, invertebrate prey. [32] The fifth digit on each hind foot is longest, facilitating swimming while on its back, but making walking difficult. [40] Researchers have noted when they approach in plain view, sea otters react more rapidly when the wind is blowing towards the animals, indicating the sense of smell is more important than sight as a warning sense. The recovery of the sea otter is considered an important success in marine conservation, although populations in the Aleutian Islands and California have recently declined or have plateaued at depressed levels. [142] Where prey such as sea urchins, clams, and abalone are present in a range of sizes, sea otters tend to select larger items over smaller ones of similar type. The southern sea otter is dark to reddish brown in color with a lighter colored head, throat, and chest. However, it frequently occurs in small groups where food sources are plentiful and will rest in a group called a “raft.”. It has a long, stout body with a short broad head and snout with thick whiskers on the cheeks. They can swim as close as six feet off shore along the Olympic coast. [172], In the Aleutian Islands, a massive and unexpected disappearance of sea otters has occurred in recent decades. [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. [128] Although abalone fisherman blamed the incursions of sea otters for the decline of abalone, commercial abalone fishing in southern California came to an end from overfishing in 1997, years before significant otter moved south of Point Conception. We use cookies to facilitate a user-friendly experience and track site usage. Sea otters, whose numbers were once estimated at 150,000–300,000, were hunted extensively for their fur between 1741 and 1911, and the world population fell to 1,000–2,000 individuals living in a fraction of their historic range. During the 1880s, a pelt brought $105 to $165 in the London market, but by 1903, a pelt could be worth as much as $1,125. [36] When at the surface, it usually floats on its back and moves by sculling its feet and tail from side to side. In some areas, massive declines in shellfish harvests have been blamed on the sea otter, and intense public debate has taken place over how to manage the competition between sea otters and humans for seafood. [115], Sea otters were once numerous in San Francisco Bay. [81] When foraging, she leaves her pup floating on the water, sometimes wrapped in kelp to keep it from floating away;[82] if the pup is not sleeping, it cries loudly until she returns. [105][106] In 1989, a separate colony was discovered in the central British Columbia coast. [9] The modern sea otter evolved initially in northern Hokkaidō and Russia, and then spread east to the Aleutian Islands, mainland Alaska, and down the North American coast. [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. Trophic Level:Omnivore. It has a long, stout body with a short broad head and snout with thick whiskers on the cheeks. [176], Sea otter habitat is preserved through several protected areas in the United States, Russia and Canada. Southern Sea Otter is a Friend in Kemono Friends 3 that appears in both versions of the game. [191], Since the mid-1970s, the beauty and charisma of the species have gained wide appreciation, and the sea otter has become an icon of environmental conservation. [176] The Toxoplasma gondii parasite, which is often fatal to sea otters, is carried by wild and domestic cats and may be transmitted by domestic cat droppings flushed into the ocean via sewage systems. Sea otters have been credited with contributing to the kelp harvesting industry via their well-known role in controlling sea urchin populations; kelp is used in the production of diverse food and pharmaceutical products. [21][22], The sea otter is one of the smallest marine mammal species, but it is the heaviest mustelid. Three separate sub species live along the coasts of Russia, Alaska, and California. [192], Sea otters can do well in captivity, and are featured in over 40 public aquariums and zoos. The sea otter was formerly sometimes referred to as the "sea beaver",[19] being the marine fur-bearer similar in commercial value to the terrestrial beaver. As members of the weasel or mustelid family, southern sea otters are the smallest marine mammal. [59] The Exxon Valdez oil spill of 24 March 1989 killed thousands of sea otters in Prince William Sound, and as of 2006, the lingering oil in the area continues to affect the population. [47] [171] Describing the public sympathy for sea otters that developed from media coverage of the event, a U.S. Currently the southern sea otter population is estimated at just above 3,000 animals. It is nursed by its mother for six months to a year, but can begin foraging in shallow water habitats as soon as six weeks after birth. [160] The Aleut population was reduced, by the Russians' own estimate, from 20,000 to 2,000. [61] Adult females move freely between male territories, where they outnumber adult males by an average of five to one. [101] In 2017 the US Geological Survey found a 3% drop in the sea otter population of the California coast. The most significant threat to sea otters is oil spills,[59] to which they are particularly vulnerable, since they rely on their fur to keep warm. To casual observers, it appears as if the animals are scratching, but they are not known to have lice or other parasites in the fur. It had stopped in the Aleutian Islands, by 1808, as a conservation measure imposed by the Russian-American Company. [16] However, because of the species' reputation for depleting shellfish resources, advocates for commercial, recreational, and subsistence shellfish harvesting have often opposed allowing the sea otter's range to increase, and there have even been instances of fishermen and others illegally killing them. [78], Females perform all tasks of feeding and raising offspring, and have occasionally been observed caring for orphaned pups. To eat large sea urchins, which are mostly covered with spines, the sea otter bites through the underside where the spines are shortest, and licks the soft contents out of the urchin's shell.
