They are also the only marine mammals that do not have blubber, a layer of fat, under their skin to keep them warm in often cold or even frigid waters. (Seals and whales are two examples of marine mammals that have blubber.) To make up for this disadvantage, sea otters have the best fur that other animals can only dream of. In fact, their fur is the world's densest, with up to 1 million hairs per square inch! Sea otters like to carry out most of their daily activities - such as swimming, resting, pooping, eating, or even sleeping - by floating on their backs. When they want to move about, they simply use their webbed, flipper-like hind legs to propel. They also use their long, flat tails to navigate.

Sea otter conservation From Wikipedia, the free encyclopedia Jump to: navigation search Sea otters in the Olympic Coast National Marine Sanctuary are descendants of otters translocated from Alaska in 1969 and 1970. Modern efforts in sea otter conservation began in the early 20th century, when the sea otter was nearly extinct due to large-scale commercial hunting. The sea otter was once abundant in a wide arc across the North Pacific ocean, from northern Japan to Alaska to Mexico . By 1911, hunting for the animal's luxurious fur had reduced the sea otter population to fewer than 2000 individuals in the most remote and inaccessible parts of its range. During the 20th century, sea otter populations recovered from remnant populations in the far east of Russia , western Alaska, and California . Beginning in the 1960s, efforts to translocate sea otters to previously populated areas were also successful in restoring sea otters to other parts of the west coast of North America. Populations in some areas are now thriving, and the recovery of the sea otter is considered one of the greatest successes in marine conservation In two important parts of its range, however, sea otter populations have recently declined or have plateaued at depressed levels.

Sea ice limits their northern range to below 57 degrees N lattitude, and the distribution of kelp forests limits the southern range to about 22 degrees N lattitude. Hunting during the 18th and 19th centuries greatly reduced the distribution fo the sea otter. Three subspecies of Enhydra lutris are recognized today.

Males weigh 60 to 70 pounds; females are 35 to 64 pounds. The length of the body and head combined is usually 3 to 4 feet, while the tail is approximately 22 to 33 inches long. characteristics Sea otters are black to dark brown except a grayish or creamy head, throat and chest. As they age, sea otters can become golden in color. Sea otters have semi-retractable claws, agile paws, and hind feet webbed and flattened into broad flippers. Unlike most marine mammals, sea otters do not have a subcutaneous layer of fat, but rely on air trapped in their dense fur for warmth. They are the only carnivores with four incisor teeth in the lower jaw. behavior Sea otters are diurnal, meaning they are active during the day. At night, they sleep in kelp beds anchored by wrapping kelp around body to keep from drifting. Females are social with no strict hierarchy. Males are territorial especially during breeding season.

Its range once extended from Baja California north then west through the Aleutian Islands, to the Kamchatka Peninsula, and south to the northern islands of Japan. In 1742, Vitus Bering's men returned with sea otter pelts from the historic voyage of discovery of Alaska. Interest in these rich furs initiated an era of exploitation which almost wiped out the sea otter. The Tlingit name for sea otters is The early Russian settling of Alaska was largely a result of the sea otter fur industry. In 1867, when Russian exploitation had greatly reduced the numbers of sea otters, Alaska was sold to the United States. The few conservation measures that had been instituted by the Russians in their final years of occupation were dropped by the Americans, and hunting intensified. Sea otters became alarmingly scarce. Finally in 1911, when so few animals were left that it was no longer profitable to hunt them (in many areas they were completely exterminated), sea otters were given full protection under the Fur Seal Treaty. The treaty was signed by the United States, Great Britain, Russia, and Japan. In 1960, the state of Alaska assumed management authority for sea otters. The management program conducted by the state included the successful reintroduction of sea otters to unoccupied habitat in Southeast Alaska, British Columbia, and Washington. The Marine Mammal Protection Act transferred management authority to the U.S. Fish and Wildlife Service in 1972.

Radio Script Recent aerial surveys show that sea otter numbers in southwest Alaska's Aleutian Islands have declined some 70 percent. (Courtesy Brenda Konar, UAF.) Sea Otter Crash INTRO: First it was sea lion populations that started to disappear along the rocky coast of southwest Alaska's Aleutian Islands. Next came harbor seals. Now scientists say sea otter numbers in the Aleutians are so low that they're likely to be listed as an endangered species before the year is out. As Doug Schneider reports in this week's Arctic Science Journeys Radio, scientists now must figure out how to save Alaska's most adorable marine mammal. STORY: The story of Alaska's sea otters reads like many of the boom-then-bust stories of the far north. In the 1740s, just before the Russians showed up in what is now Alaska, sea otters were thought to number in the hundreds of thousands. Over the next 170 years, hunting by the Russians, and then the Americans, pushed the sea otter to the brink of extinction. By the time hunting was banned in 1911, sea otters were all but extinct across Alaska. To help sea otters recover, scientists in the 1960s transplanted several hundred animals from surviving groups in Prince William Sound and the Aleutian Islands to Southeast Alaska, where the situation was most dire. Soon, sea otters were once again thriving at or near their historic highs across the state. According to the Alaska Department of Fish and Game, sea otters in the Aleutians alone numbered around 100,000 animals by the 1970s.

40. Killer Whales Feeding On Sea Otters: 10-19-98 Tim Stephens explains how overexploitation of certain North Pacific and Bering Sea fisheries may have initiated a cascade effect that is pushing the sea otter towards extinction in the waters of Alaska. Features an overview of UCSC research into the phenomenon. http://www.ucsc.edu/oncampus/currents/98-99/10-19/killer.htm

October 19, 1998 Killer whales feed on sea otters, pushing coastal ecosystems off kilter By Tim Stephens UCSC researchers find killer whales have begun preying on sea otters, causing widespread disruption of coastal ecosystems in western Alaska Killer whales are feeding on sea otters in the absence of their traditional prey. ( More photos With seals and sea lions in short supply in the North Pacific, killer whales are now feeding on sea otters, causing an abrupt decline in sea otter populations in western Alaska, according to UCSC researchers studying the area's marine ecosystems. The decline in sea otters has allowed their primary prey, sea urchins, to increase in number and strip coastal kelp forests over large areas, said James Estes, a marine ecologist with the U.S. Geological Survey and UCSC. The new phenomenon of killer whales preying on sea otters appears to be one link in a chain of interactions extending from the open sea to the coastal zone and involving a wide range of species at different levels of the food chain. Overexploitation of certain North Pacific and Bering Sea fisheries may have initiated this cascade of ecological effects, Estes said. Estes and his coworkers reported their findings in the October 16 issue of the scientific journal Science.
