  2. The only living member of the genus Enhydra, the sea otter is so different from other mustelid species that, as recently as 1982, some scientists believed it was more closely related to the earless seals
  3. Sea otters are further divided into three subspecies: E.l. lutris - the Russian or Asian sea otter E.l. kenyoni - the northern or Alaskan sea otter E.l. nereis - the southern or California sea otter
  4. otter genera. The sea otter is the only member of the genus Enhydra. Each genus is a monophyletic group, meaning that the organisms in each genus share a common ancestor. The sea otter is sister to the speckle-throate
  5. Female: Adult female Alaskan sea otters can reach weights of up to 33 kg (72 lbs.), and female California sea otters weigh on average 20 kg (44 lbs.) Diet. A sea otter has a metabolic rate much higher than most mammals of similar size, and must consume large quantities of food. Adult sea otters may eat as much as 9 kg (20 lbs.) of food each day

The Sea Otter's scientific name is Enhydra lutris, which means otter that lives in the water. This species is aptly named because sea otters rarely come on land. This animal is the largest otter species by weight. Adults range in weight from 50-100lbs and grow to 4-5ft from head to tail tip Two sea otter subspecies occur in the United States, the southern sea otter (Enhydra lutris nereis) and the northern sea otter (E.l. kenyoni). Southern sea otters, also known as California sea otters, live in the waters along the central California coastline

The scientific name of the sea otter is Enhydra lutris. Enhydra appears to come from an old Greek term that roughly translates to in water. The scientific name Lutris is simply the Latin word for otter. The sea otter is only one of 13 otter species, but it's also the only living member of its genus The sea otter is the largest member of the weasel family. Their fur is made up of a dense underfur, ranging in color from brown to black, and longer guard hairs. The guard hairs can be brown to black to silver. Their hind feet are webbed to aid in swimming, and their front toes are short and stiff The sea otters were scientifically described for the first time by the German zoologist Georg Steller (March 10, 1709-Tiumén, November 14, 1746)) in field notes in the year 1751.. A few years later, the Swedish botanist Carlos Linnaeus (May 23, 1707-January 10, 1778) also described them in his work Systema Naturae which was written in 1758.Their current scientific name Emhydra Lutris was.

A newborn southern sea otter pup is a buff color, 22 to 24 inches (55 - 60 cm) in length and 4 to 5 lbs. (1.8-2.3 kg). The southern sea otter is dark to reddish brown in color with a lighter colored head, throat, and chest. It has a long, stout body with a short broad head and snout with thick whiskers on the cheeks The genus name, Enhydra, comes from the Greek for in water; the species name, lutris , from the Latin word for otters; and the subspecies name of the southern sea otter, neresis, means sea nymph or swimmer

  2. Two otter species are strictly marine: the sea otter (Enhydra lutris) of the Pacific Coast of North America and the much smaller marine otter (Lontra felina) from the coast of Peru and Chile
  3. Sea otters are a medium-sized member of the Mustelidae family. The largest of this weasel family, sea otters weigh 31-100 lb (14-45 kg). Their fur is brown with shades of lighter tan and yellow on the heads of adults. They have long whiskers, small ear flaps, and two small black eyes
  4. Clawless otters (genus Aonyx) specialize on crustacean s (especially crabs) and mollusk s, whereas other otters (genus Lutra) are primarily fish eaters. Specialization even occurs between sexes in the weasels (genus Mustela), in which males consume larger prey than females owing to their larger size
  5. Sea otters, Enhydra lutris, are found in two geographic regions on the Pacific Coast: along the Kuril and Commander Islands off the coast of Russia, the Aleutian Islands below the Bering Sea, and the coastal waters off the Alaskan Peninsula to Vancouver Island, Canada; and along the central California coast from Ano Nuevo to Point Sur

The sea otter fits all of these characteristics and also is active year round like members in this family. All sea otters belong to the genus Enhydra. The sea otter is the only member of this genus. This particular species is given the scientific name of Enhydra lutris The Sea Otter is a specie from the Enhydra genus. It is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. 1 Appearance 2 Behaviour 2.1 Diet 2.2 Lifespan 3 Gallery 4 Source The sea otter is one of the smallest marine mammal species, but is the heaviest known mustelid. Male sea otters usually weigh 22 to 45 kg and are 1.2 to 1.5 m in length, though specimens. The Southern Sea Otter got it's name by looking like a marine fur-beaver because they look almost the same. The Southern Sea Otter's scientific name is Enhydra lutris which was named by Carl.. Until recently, the spotted-necked otter was considered to be part of the Lutra genus, but it is now placed in the Hydrictus genus. It is common in Lake Victoria and Zambia, but not in some lakes and rivers, such as in the Zambezi below the Victoria Falls

Genus: Steno Steno bredanensis (Rough-toothed dolphin As members of the weasel or mustelid family, southern sea otters are the smallest marine mammal. Like other members of this family, they have very thick fur. In fact, at 850,000 to 1 million hairs per square inch, sea otters have the thickest fur of any mammal. Their fur actually consists of two layers, an undercoat and longer guard hairs

  1. ks, and of course, otters. Sea otters belong to the Enhydra genus and Lutris species, which is why their scientific name is Enhydra lutris. I have studied the details of the Enhydra lutris organism and pieced together a presentation.
  2. Southern Sea Otter. Southern sea otters (Enhydra lutris nereis), also known as California sea otters, were listed as threatened in 1977 under the Endangered Species Act. Reduced range and population size, vulnerability to oil spills, and oil spill risk from coastal tanker traffic were the primary reasons for listing
  3. Population. Sea otter numbers have declined in southwestern Alaska over the past 20 years. 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
  4. These otters are characterized by more blade-like carnassials, unlike the other group of otters, the bunodont otters. Bunodont otters possess non-blade-like carnassials with thick enamel and rounded cusps. The bunodont otters include the extant genus Enhydra (sea otters) as well as the extinct genera Enhydritherium and Enhydriodon (Lambert, 1997)

  7. Sea otters are the smallest representatives of the genus Lontra. The length of the body varies from 57 to 78.7 centimeters, but taking into account the tail, it can reach up to 87-115 centimeters

The Southern sea otter is known as Enhydra lutris nereis, the Russian sea otter is Enhydra lutris lutis the Alaskan sea otter is Enhydra lutris kenyoni, and the Asian sea otter is Enhydra lutris gracilis. While there are four subspecies, I will only be talking about the Southern and Alaskan sea otters due to lack of information on the other. 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). Wild sea otters typically have a lifespan between 15 and 20 years. Average weight of an adult female California sea otter is about 50 lbs. Males can weigh up to 70 lbs

Sea otters can breed twice a year. Most females produce a single pup. The pup weighs between 1.5 and 2.5 kg. There are instances of twins, but they are rare. However, it has been observed that in the case of twins, only one pup survives.

Sea otters are the only species in the genus Enhydra and belong to the order Carnivora, suborder Caniformia and family Mustelidae (ITIS 2017). Three subspecies are recognized, based primarily on skull and dental characteristics: E. l. kenyoni from the Aleutia Vulnerabilities. Sea otters may be fierce predators but they have a number of physiological characteristics that make them particularly vulnerable to disturbance. In particular, sea otters have a very high demand for energy and spend a large portion of their time resting to conserve energy and foraging to get energy Sea otters, Enhydra lutris (Linnaeus, 1758), are the largest member of the Family Mustelidae (70 species of river otters, skunks, weasels, badgers, etc.) and are the smallest marine mammal in North America.
