Most of a Sea Otter's day is spent feeding, grooming, or resting, usually in that order. In addition to the underwater noise, the ferry poses a real danger to divers. Frequent grooming activity prevents soiling of the fur, loss of insulation, and reduced buoyancy. Normal speeds are 1 to 5 km an hour; the maximum about 9 km an hour. Two species of otters occur in British Columbia - the Sea Otter and the more widespread River Otter. Food items are normally clasped between tough leathery pads of the two forepaws and brought to the surface to eat.

It is the only mammal other than the primates (monkeys, apes, humans) known to use tools. They are much more buoyant … Fun Facts. White or transparent. River Otters frequent rivers and lakes, but are also common in saltwater along the entire British Columbia coast. Sea Otters dive to the seafloor to obtain a variety of invertebrate animals. When lying face-up they move slowly by sculling the tail or paddling with one or both hindlimbs. With their elevated metabolic rates, sea otters must consume large quantities of these invertebrates and thus they have high exposure rates to the associated parasites and pollutants. An Ecological Reserve covering all of Checleset Bay (the Sea Otter release site) was established by BC Parks in 1981, and harvest closures on many key shellfish eaten by the otters (clams, sea urchins, abalone) have been instituted in the reserve by the Department of Fisheries and Oceans Canada (DFO). Close to Loomis, Roseville, Rocklin, Lincoln, Auburn, … The ingenious Sea Otter uses rocks as tools to break open hard-shelled prey or to dislodge prey such as abalone. During 126 years of Russian control, more than 800 000 are believed to have been taken in Alaska alone. Many areas that were otter-free for decades, particularly rocks and reefs, have dense populations of sea urchins and little or no kelp (large algae), this having been eaten by the grazing urchins. There were three releases totalling 89 Sea Otters (taken from Amchitka Island and Prince William Sound) at the Bunsby Islands in Checleset Bay, on Vancouver Island, during this time. An acute sense of touch, using paws, nose, and whiskers, is very important for finding prey in crevices or bottom sediments, and during dim light. A “keystone species” is a species that is critical to how an … Otters ( lutra) are carnivorous mammals in.

Almost all otters have webbed feet, some more webbed than others, and they can close off their ears and nose as they swim underwater. This may also happen in other areas. Otters in Washington and British Columbia, where populations are small and food is abundant, may spend as little as 10 or 15 percent of their day feeding, compared to 50 or 60 percent at Amchitka Island, where otter numbers are high and readily available foods have been exhausted. Following reintroduction, the Sea Otter population in Canada has increased to about 900 animals and has been growing at a rate of 17 to 20 percent per year. We are committed to providing an environment where your child feels safe enough to try new things and accomplish goals.Â. When dry, the fur on the head is cinnamon to light brown.

It is not too difficult, especially in poor vis, for a diver to get disoriented and end up swimming into the ferry lane. Sea otters are unusual among marine mammals in that they live outside of their zone of thermal neutrality and consequently have extremely high metabolic demands. Search for "otter swimming" in these categories. Next. Pups receive a lot of maternal care and training until almost adult size, a period of six to eight months or more. The tail is about one-third the length of head and body; the River Otter's is about twothirds. Complex coastlines having many islands, reefs, bays, and points provide a variety of feeding sites and shelter from storms, and appear to support the highest numbers of otters. Research at Checleset Bay, Vancouver Island, and elsewhere has shown that introduced Sea Otters greatly reduce the urchin populations, allowing extensive stands of kelp to develop. The reintroduced British Columbia population, possibly with the help of animals from northern Washington and southeast Alaska, may eventually expand their range into this vacant habitat. 's Sea Otter is good, although present populations are still relatively small and vulnerable. We quickly realized that Sea Otter would teach swimming and water safety skills in a fun and safe environment. Small amounts of oil, by affecting insulation, can cause hypothermia for Sea Otters, and any major spill, an ongoing threat on the B.C. Although young may be born at any time of year, most births occur in spring or early summer. The estimated gestation period is 6W to 9 months.

Male rafts are usually larger (up to 100 or more in Alaska); but female rafts may contain up to 40 adults with their pups. An estimated 150 000 or more now occupy most of their original range from the Kuril Islands to Prince William Sound, and the isolated remnant in California has increased to about 2000. A sea otter’s fur contains an estimated 650,000 hairs per square inch. Moreover, a large proportion of their diet consists of filter-feeding benthic invertebrates, which tend to concentrate both contaminants and disease-causing pathogens that flow into near-shore waters from land. Once extinct on our coast, Sea Otters are now expanding to reoccupy their former habitats and to resume their role in the ecology of B.C.

Females can give birth any time of the year, but most in California have their pup between January and March. This was a cooperative effort involving BC Environment (Fish and Wildlife Branch), Fisheries and Oceans Canada (Pacific Biological Station), Canadian Armed Forces (Search and Rescue, Comox), U.S. Bureau of Sport Fisheries and Wildlife, Alaska Fish and Game Department, and U.S. Atomic Energy Commission.
