	Walrus - Wikipedia, the free encyclopedia
		Walruses are large semi-aquatic mammals that live in the cold Arctic seas of the Northern Hemisphere.
		Pacific walruses spend the summer north of the Bering Strait in the Chukchi Sea along the north shore of eastern Siberia, around Wrangel Island, in the Beaufort Sea along the north shore of Alaska, and in the waters between those locations.
		Walruses spend about half their time in the water and half their time on beaches or ice floes where they gather in large herds.

		Since Stewart would rather not immobilize female walruses because of the effects the drugs may have on pregnant or lactating females and their calves, the next challenge is to locate a suitable adult male.
		Walruses are bottom feeders and generally graze on slow-moving prey in waters no more than 250 feet deep; several species of clams comprise the majority of their diet.
		Walruses spend the majority of their lives in the water, but they are highly dependent on ice.

	Walrus - Fact Sheet (Site not responding. Last check: 2007-09-19)
		Generally walruses occupy first-year ice with natural openings such as leads and polynyas and are not found in areas of extensive, unbroken ice.
		The factors affecting the resumption of estrous cycles in walruses are unknown; however in some mammals estrus is suppressed during lactation by elevated levels of the pituitary hormone prolactin which is produced and maintained in response to the suckling stimulus.
		Walruses are preyed upon by polar bears, killer whales, and man. The magnitude of natural mortality is unknown but is assumed to be low, given the population's low productivity.

	SCS: Walrus (Odobenus rosmarus)
		Walruses are long-lived and have a relatively low reproductive rate, so their numbers are easily influenced by hunting and other mortality.
		Walruses are also conservative in their choice of habitat and food, so any reduction in these may have detrimental effects on their numbers.
		Walruses are particularly at risk from oil spills as their staple diet of benthic invertebrates are known to accumulate hydrocarbons.

		Like sea lions, walruses can turn their hind flippers forward for walking on land; their foreflippers are weaker than those of sea lions and they are not as strong swimmers.
		Walruses use their tusks for prying shellfish from the ocean floor, as well as for pulling themselves up onto ice floes.
		Walruses have been very important in the economy of the Eskimo, who hunt them for food and clothing; the introduction of firearms greatly increased the size of the kill.

		This feeding pattern makes walruses unique among pinnipeds, and has led to different theories as to how the walruses are able to locate and excavate their benthic prey [5-8].
		The feeding grounds are accessible to the walruses from ice break-up at the end of July until the formation of new fast-ice in October [9,10].
		In some recordings the walruses appeared to be using their eyesight; the eyes were actively kept focusing towards the feeding spot often in combination with vigorous use of the vibrissae to provide tactile information.

	Discovery Channel :: Walruses Prefer Right to Left
		Walruses are highly specialized feeders, eating bivalve shellfish that burrow up to 16 inches deep in sand and sediments on the sea floor.
		The recordings revealed that the walruses use three different foraging behaviors to find the shellfish: swishing away sediment by beating a flipper; removing sediment by squirting a water-jet from the mouth; or rooting pig-like through sediment with the muzzle.
		But when they were actively seeking out shellfish using their favored flipper-beating technique, the walruses used their right flipper — a trait known as dextrality — 89 percent of the time.

		Noting that the application stated that the walruses collected would be orphaned "as a result of weather, accident or by the authorized native subsistence harvest," the commission recommended that the zoo be required to explain the circumstances surrounding the orphaning of each walrus and that compensation not be offered that might induce intentional orphaning.
		And because the walruses were removed from their natural environment, they could not behave normally or be displayed properly so the public wasn't going to learn anything meaningful from them, Laidlaw said.
		Female walruses also are more desirable in some situations because their skin often is better for making skin boats, used to hunt whales, as it has fewer tears and holes, he said, adding that there were only about 20 such boats in each village.
