To keep warm, sea otters spend a large portion of their days grooming and conditioning their fur. While eating, an otter will roll repeatedly in the water to wash away food scraps from its chest. Mating and breeding do not occur in the sea. Sea otters are ‘’keystone species” because of their critical role in maintaining the health and stability of the nearshore marine ecosystems. Scientists suggest that this adaptation may help mothers give birth at the most opportune time of year—when food is most abundant, for example. If a male doesn’t get the warm reception he was looking for from a female he will move on to find another one. Some males will hold otter pups hostage until the mother pays a ransom of food to the male. Sea otters are highly specialized marine mammals capable of living their entire lives without ever having to leave the ocean, have the densest fur of any mammal and are one of the few marine species to use tools. 8.) Sea otters are an apex predator of the nearshore ecosystem. This system traps a layer of air next to their skin so their skin does not get wet. Spring survey results are used as an indicator of the population trend of California sea otters.

Sea otters often rest together in single-sex groups called rafts. At birth, pups are approximately 2 feet (.6 m) in length and weigh 4-5 lbs (2-2.3 kg). The sea otter’s hind feet are webbed and flipper-like, and are used in conjunction with its lower body to propel the animal through the water. Male sea otters will sometimes kidnap sea otter pups and hold them underwater until the female gives him her food. Male and female sea otters often live apart. Breeding males defend territories within the female areas, while other males–juveniles and non-breeding adults–occupy the … Fur: A sea otter's fur is the thickest and finest of any mammal. The pups are very helpless at birth as they are blind until they are about a month old. Prey specialization and feeding preferences are passed on from mother to pup.

Length and Weight: Adult male sea otters weigh 70 - 90 pounds (32 - 41 kg) with some individuals reaching 100 pounds (45 kg). Sea otters also rape baby seals to death. 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). Individuals typically remain solitary, however groups are often formed while resting. It has the thickest pelt in the animal kingdom. 9.)

Otherwise the two sexes generally stay separated with the exception of the young males remaining with their mother for a few years. In expanding populations, which is the case in BC, male sea otters are the first to investigate new, prey-rich areas.

The short, brown underfur can be as dense as 1 million hairs per square inch, making its fur the densest of any mammal. do otters rape? Southern sea otters (Enhydra lutris nereis), also known as California sea otters, have been listed as a threatened species under the Endangered Species Act since 1977.

Instead they depend on their dense, water-resistant fur to provide insulation. Numbers in these male areas tend to increase in winter and spring because there are fewer mating opportunities with sexually receptive females during this time of the year. An otter must consume approximately 25% of its bodyweight in prey each day just to stay alive (for a 75 pound kid, that would amount to eating 75 quarter pound hamburgers every day!). Other vocalizations include:  coos and grunts, which occur when an animal is eating or when content, as in the case of a pair-bonded couple during courtship;  whines occur when an animal is frustrated, as in the case of an older pup wanting to suckle or an adult male attempting to mate with an uninterested female;  growls, snarls, whistles and hisses can be heard when an animal is frightened or distressed, as in the case of a captured otter. Factors that can influence the count include viewing conditions, abundance and species composition of surface canopy kelp, observer experience, and distribution and movements of the animals. The second subspecies of northern sea otter, E. lutris lutris, inhabits the Commander Islands of the Bering Sea, the coasts of the southeastern Kamchatka Peninsula and the Kuril Islands in Russia, and the northern coast of Japan. Size Alaskan sea otters are slightly larger than California sea otters Female: Female Alaskan sea otters measure up to 140 cm (55 in.)

Sea otters spend most of their time floating on their backs at the surface grooming, eating, resting, and diving for food on the seafloor. The southern sea otter population has grown slowly since that time, but it has exhibited high levels of mortality in recent years. Sea otters are polygynous; stronger males establish territories with high numbers of females and work to exclude other sexually mature males.

Male sea otters live up to about 15 years and females live up to 15-20. A range-wide census is conducted each spring to monitor trends in abundance and distribution of the southern sea otter, providing State and Federal agencies with the information they need for effective management. Sometimes it would even weigh up to 30 kilograms. and resting bout follow at mid day. River otters are more petite. The dental formula is I 3/2, C 1/1, P 3/3, M 1 / 2; total 32. This study should help us reduce river otter mortality so we can continue to enjoy seeing them as they go … If cold ocean water reaches their skin, it will immediately begin to draw heat out of the animal, which disrupts the animal’s ability to thermoregulate and will ultimately lead to hypothermia and death. Sometimes females drown during mating. Learn more about these cute and charismatic critters. To reduce the influence of anomalously high or low counts during any particular year, three-year running averages — commonly called a “population index” — of the survey results are also used to assess whether the population is growing or declining.

Different to river otters, the female otters would only weigh around 5 kilograms up to 10 kilograms. This type of courting takes place on land. Mothers have have been known to carry their pup for several days after the pup’s death. Fish and Wildlife Service. (19.8 kg). The population index is also used to determine the species’ official listing status under the Endangered Species Act and what threshold has to be met for the species to be “delisted.” For southern sea otters to be considered for removal from threatened species listing, the population index would have to exceed 3,090 for three consecutive years, according to the threshold established under the Southern Sea Otter Recovery Plan by the U.S. The male sea otters will swim around and search for females in oestrus .
