Extractions: We will be living in a comfortable log cabin nestled in the spruce and hemlock tress overlooking Alice Cove. Despite its remote location, the cabin has a living/working area, fully equipped kitchen (propane stove and oven), RV-type toilet (supplemented with an outhouse), and hot shower (showering will be limited to 3 minutes/person/day). The cabin is heated with either wood or oil-burning stoves. Fresh water is plumbed into the cabin from a nearby stream. A generator and a bank of 12-volt batteries provide electrical power. Volunteers will sleep in heated Weatherport or house-tents erected on platforms near the cabin. Meals will consist mainly of food purchased in Cordova and brought to Alice Cove. Volunteers and staff will prepare food using pre-arranged menus, and we will eat dinners as a group.

Extractions: Sea otters are sleek, furry, streamlined marine mammals that live along rocky Pacific Ocean coasts, bays, and kelp beds. They are found from the coast of California through Alaska and along the eastern coast of Russia to northern Japan. This type of weasel spends most of its time in the water, where it is fast and graceful; it is slow and awkward on land. The scientific name is Enhydra lutris (Genus species). The sea otter is a protected species because of previous overhunting (they were once hunted for their thick, dense fur). Anatomy : Sea otters are up to about 4 feet (1.3 meters) long and weigh from 45 to 82 pounds (20-37 kilograms). They have webbed hind feet which they use to swim; the forefeet are smaller. The claws are semi-retractible. The ears and nostrils close when the otter is underwater. Sea otters sleep and rest on their backs, usually anchored in a kelp (seaweed) bed. Fur : Sea otters are kept warm in the cold Pacific Ocean by their dense fur and high metabolism; they are the only marine mammal that has no layer of insulating fat. Sea otters have the densest fur of any mammal; the coat has over half a million hairs per square inch. Careful grooming with the forepaws keeps the fur waterproof. Oil spills cause the fur to lose its waterproof quality, causing the sea otter to get hypothermia, usually killing it. Diet : Sea otters are carnivores (meat-eaters). They eat

http://www.discoverlearning.com/webjourneys/otters/

Extractions: Sea otters live in kelp forests and bays along the coasts of the north Pacific Ocean. The only sea otters near Vancouver live at the Vancouver Aquarium Marine Science Centre. Sea otters Milo and Nyac are permanent residents at the Aquarium and are always a treat to visit. Milo is short for Milenio. Milo is a male sea otter whereas Nyac is a female. In areas where the sea life that killer whales normally prey on is becoming scarce, killer whales have started eating sea otters. Eagles will also capture and eat young sea otters. Oil spills are particularly damaging to sea otter populations. Nyac is actually a survivor from the Exxon Valdez spill. The Exxon Valdez spill happened in 1989 when an oil tanker ran aground in the Prince William Sound off Alaska, spilling 232,000 barrels of oil into the ocean. She is providing valuable information on the long-term survival of animals exposed to oil. In the 1700s and 1800s fur traders hunted sea otters to extinction along the British Columbia Coast. Since then it has been made illegal to hunt sea otters. Milo and Nyac are pleased about the government protection but oil spills are a constant worry for their relatives along the coast. Only one tablespoon of oil on a sea otter's fur will reduce the otter's ability to keep warm and it will die quickly.
Those Naughty Sea Otters
Those Naughty sea otters. I'm not overly fond of sea otters. There, I said itand I'm glad. But do sea otters exhibit such responsibility? I think not.
http://www.id.ucsb.edu/lovelab/otter.html

Extractions: There, I said it and I'm glad. In fact, I am more than glad. Suddenly, I have the lightness of spirit normally reserved for winning Olympic athletes, pilgrims in sight of the Promised Land and the criminally insane. Yes, yes, I know otters are cute, with their little squashed-in faces, hand-like paws and black button noses. And yes, I have seen all of those adorable little mannerisms: the paw-waving, the superciliosus smiles, the grooming; all of which inevitably evoke ooshy-gooshy responses in easily-swayed humans. And I also realize they are a growth industry in central California; tourists here gobble up sea otter curios like so much jalapeno-flavored popcorn. Every bar in Monterey offers "Sea Otter Margaritas", every trinket shop sells battery-operated plastic sea otter dolls that smash plastic rocks against plastic abalones and every department store pushes "Mother and Baby Sea Otter" garlic shredders made out of genuine redwood burl. Despite this outpouring of emotion, I still think otters are overrated. Now, I don't want a flood of anguished letters calling me bad names and casting aspersions upon my character. For one thing there's not that much to cast aspersions upon. So, save yourself some time. Don't hobble over to your writing desk, pull out that hideous monogrammed stationary, put quill to paper and pen some quasi-coherent complaint. I'm not suggesting we turn otters into hats. I just think the hoopla is overblown.
EVOS-Oil Spill Facts-Status Of Sea Otters
Detailed information about the current status of sea ottersin the Exxon Valdez oil spill region.
http://www.oilspill.state.ak.us/facts/status_seaotter.html

Extractions: By the late 1800s, sea otters had been eliminated from most of their historical range in Alaska due to excessive harvesting by Russian and American fur traders. Surveys of sea otters in the 1970s and 1980s, however, indicated a healthy and expanding population in most of Alaska , including Prince William Sound Today the only harvests of sea otters are for subsistence purposes. About 1,000 sea otter carcasses were recovered following the spill, and additional animals probably died but were not recovered. In 1990 and 1991, higher-than-expected proportions of prime-age adult sea otters were found dead in western Prince William Sound , and there was evidence of higher mortality of recently weaned juveniles in oiled areas.

Law and Policy Giant kelp has no roots, yet can grow to 200 feet, and is the world's largest and fastest growing plant in the sea. Sea Otters Sea otters average four feet in length and weigh between 40-60 pounds. While their bodies are adapted for water - they have flipper-like hind feet and broad flat tails - sea otters are actually quite slow swimmers when compared to other marine mammals. Unlike most marine mammals, sea otters lack a thick layer of fat to insulate them from cold temperatures. Instead, they have an extremely dense coat of fur which helps to trap a layer of air close to their skin to keep them warm. Female sea otters are ready to bear young at three to four years, and normally give birth to one pup. Since pups are heavily dependent upon their mothers for up to one year, sea otters usually reproduce every other year. Sea otter pups are typically two feet in length and weigh between three and five pounds at birth. Southern sea otters are found along the central coast of California. They eat sea urchins, mollusks, squid, crabs, and clams. Their teeth are specially adapted to eating shellfish, allowing them to crush shells and scoop out meat. They will occasionally eat finfish, but their rounded teeth lack the sharp edges necessary to handle the slippery prey.

Extractions: Sea otters once lived along most of the coastal North Pacific Ocean. That was before fur traders hunted them for their thick, luxurious pelts. By the year 1900, sea otters were nearly extinct. Today they're protected. The California population is still smallabout 2,000 sea otters spread over only about 226 km (140 mi.) of central California coastline. California sea otters are listed as "threatened" under the Endangered Species Act.

Population Today there are fewer than 2,000 southern sea otters off the coast ofCalifornia. Southern sea otters typically reach about four feet in length.
http://npca.org/marine_and_coastal/marine_wildlife/seaotter.asp

Extractions: Factoid: The sea otter has the thickest fur in the animal kingdom. Status: Threatened off California. Population: Today there are fewer than 2,000 southern sea otters off the coast of California. Almost 150,000 northern sea otters inhabit the coastline of Alaska, and there are approximately 9,000 in Russia (Siberia). Two hundred years ago, demand for the otter's pelt nearly led to its extinction. Threats: Oil spills, habitat loss, plastic entanglement, and conflict with abalone fishermen. Survival: The average sea otter lives 10 or 11 years. Unlike other marine mammals, the sea otter does not have a layer of blubber (fat) to help keep it warm. If an otter's fur gets coated with oil or any other substance, the otter can easily die from cold and exposure. The sea otter is the largest member of the weasel family. Southern sea otters typically reach about four feet in length. Females average 45 pounds, while males average 65 pounds. Alaskan or northern sea otters can reach up to 100 pounds.

Extractions: In a matter of years, aquariums could be the only place people regularly see sea otters, say many marine scientists. After a strong recovery for most of the last century, sea otters are declining in California and across much of their range, particularly in the remote Aleutian Islands of the North Pacific. 'Sea otters are going down the road to ecological extirpation,' said Jim Estes, a Santa Cruz-based scientist for the U.S. Geological Survey who has long studied the Aleutians. Sea otter recovery, he said, was one of the great conservation successes of the century. 'Now we are seeing it lost in our lifetime,' he said.

http://www.alaska.com/akcom/trivia/trivcom/bio/story/1810373p-1925916c.html

Extractions: Answer: The sea otter belong to the weasel family, along with the river otter and the mink. Adult males can reach 100 pounds and females 60 pounds, a weight belied by the gracefulness with which they float and dive. These whiskered swimmers are a favorite of kayakers and tour boat passengers. Russian crews first came to Alaska to collect sea otter pelts, said to be possibly the finest fur in the world, and nearly took the population to extinction. The pelt has dense underfur of brown, inch-long hair and sparse guard hairs. Older sea otters often develop a silvery head. Sea otters are adept at handling food with the toes on their front feet, feeding themselves sea urchins, crabs, clams, mussels, octopus and fish. After diving as far as 250 feet down and returning with food, they roll onto their backs, put the food on their chests and eat it piece by piece. Wild sea otters never eat on land.

http://www.sheddnet.org/ani_faqs_01.html

Extractions: How do Alaska sea otters keep warm if they don't have blubber? Alaska sea otters depend on their fur and a fast metabolism for protection from the cold. The fur is made up of outer guard hairs and extremely dense under fur. When the otters groom, they trap air at the base of the under fur to provide an insulating layer of air between their skin and the cold water. The guard hairs cling together, forming a protective covering that helps to keep the under fur dry. Natural oils in the fur also help to repel water. The fur must be clean and meticulously groomed. A sea otter also has an extremely fast metabolism. An adult eats the equivalent of 20 to 25 percent of its body weight daily, which amounts to about 17 pounds of food for an adult male.

http://www.calacademy.org/calwild/pacdis/issues/fall96/otter.htm

Extractions: FALL 1996 The young California sea otter was sleeping soundly in her usual spot in Monterey Harbor. It was Female 515, also known as Josie, who had been raised here by her mother, amid the constant boat traffic and human activity. I watched with interest as a couple of kayakers glided by and stopped. I knew they might be in for a surprise, for Josie was a notorious harasser of kayaks and small rowboats, on which she liked to hitch rides. She seemed to find this particular type of kayak, which lies very low to the water, especially irresistible. By now the otter was staring intently at the kayakers. Josie stretched, twirled in the kelp and dove, disappearing beneath the glassy surface. Almost half a minute passed. Everything was quiet and the kayakers had started to paddle away. Suddenly, the otter exploded out of the water and landed on the back of one kayak, nearly tipping it over. I could see the shock and surprise on the kayaker's face. He'd probably been warned not to disturb or harass sea otters in any way, and he must have seen the posted signs cautioning people to stay at least 50 feet from the shy and easily disturbed otters. But Josie made this rule a little difficult to obey. As the man struggled to keep his balance, the young female slid off his boat and headed for the other kayak, but its occupant wasn't waiting around. He sprinted off as fast as he could, with Josie in hot pursuit. Since sea otters can swim up to six miles an hour in short bursts, it took a good two minutes of frantic paddling for him to outdistance her.
Ocean Quest! Sea Otters
sea otters were one species of animals that was affected by the oil spill. Therewere 400 sea otter rehabilitation volunteers and many more otters.
http://www.kpbsd.k12.ak.us/seward.elem/ocean/seaotter.html

Extractions: Seward Elementary School On March 24, 1989 the Exxon Valdez ran aground and the oil traveled far into Prince William Sound. Sea otters were one species of animals that was affected by the oil spill. There were about 400 sea otter rescue volunteers. The first thing that they needed to do was catch the otters. There were two ways that the people caught the otters; one way was that they would look through binoculars and find the otters that look distressed. Then they would take little boats out and trap the otters on land, where they couldn't move as fast as in the water. Another way that they could catch the otters was they found the place where the otters were most likely to swim through, then they would put a net down and catch the otters. They checked the net every hour or so. Sometimes, the fumes from the oil would make the collectors so drowsy it was very hard for them to collect the otters. In relation to the oil spill, it wasn't until 24 hours after the oil spilled that they helped the otters. After many otters were collected the people brought them to a large rented gymnasium in Valdez. One thing that was bad about having the otters out of the water was that they would get pressure sores from resting on plywood, plastic grates, and wire mesh. Sometimes, to improve the otters skin and fur they would put them in salt water pools or floating pens. The workers cleaned the tanks out about every 3 days.
