Bulls will display by throwing their heads back and freezing with their tusks in the air, and making chiming noises by pushing air back and forth in theirpharyngeal pouches. Ears, located just behind the eyes, are small inconspicuous openings with no external ear flaps. While some of these uses have faded with access to alternative technologies, walrus meat remains an important part of local diets,[92] and tusk carving and engraving remain a vital art form. Increased tear production. [41][42][43][44][45][46][47][48][49], In 2006, the population of the Pacific walrus was estimated to be around 129,000 on the basis of an aerial census combined with satellite tracking.

They use their tusks for cutting through ice and getting out of the water, as well as defence and for males, to demonstrate dominance. [30] While the dentition of walruses is highly variable, they generally have relatively few teeth other than the tusks. There is disagreement over the classification of the taxonomic group Pinnipedia. With these pouches inflated they can rest effortlessly on the surface, and will even sleep in the water with their heads tossed back, bobbing dreamily. [23] Length typically ranges from 2.2 to 3.6m (7ft 3in to 11ft 10in). Walruses are very fat, but for good reason.

Walruses' scientific name (Odobenus) translates from Latin into "tooth walking sea horse". Why do walruses have red eyes? Although it would seem to make sense, recent research shows walruses do not use their tusks when foraging in the deep sea. Females in estrus will gather in groups on the beach, and males will stake out territories on the coastline and try to attract them. In these coastal areas, there is less food, conditions may become crowded, and the walruses are more susceptible to predation and human activities. [34] Calves are born during the spring migration, from April to June. [73] However, it prefers benthic bivalve mollusks, especially clams, for which it forages by grazing along the sea bottom, searching and identifying prey with its sensitive vibrissae and clearing the murky bottoms with jets of water and active flipper movements. Tusks can be as long as 3 feet (0.9 m) for males! During the 19th century and the early 20th century, walrus were widely hunted for their blubber, walrus ivory, and meat.

Walruses appear to have whiskers because of their bristles connected to their snout, called vibrissae 33. [4] They are not particularly deep divers compared to other pinnipeds; the deepest dives in a study of Atlantic walrus near Svalbard were only 3117m (102ft)[72] but a more recent study recorded dives exceeding 500m (1640ft) in Smith Sound, between NW Greenland and Arctic Canada - in general peak dive depth can be expected to depend on prey distribution and seabed depth. When walruses enter cold water they become paler still, as blood flow to the skin is reduced. Walruses need ice for hauling out, resting, giving birth, nursing, molting, and protecting themselves from predators. And that's life with the ice for walruses. The walrus's scientific name is Odobenus rosmarus. Baby walruses are well developed when born with fur and open eyes, and they can swim within about an hour. [54] The Atlantic walrus once ranged south to Sable Island, Nova Scotia, and as late as the 18th century was found in large numbers in the Greater Gulf of St. Lawrence region, sometimes in colonies of up to 7,000 to 8,000 individuals. Other causes of eye injuries include: Physical sports such as football, rugby, tennis, etc. [31], Aside from the vibrissae, the walrus is sparsely covered with fur and appears bald. Because skin blood vessels constrict in cold water, the walrus can appear almost white when swimming. The greatest threat to walruses is climate change Melting sea ice means more Pacific walruses are resting on land, further from their feeding grounds. The new year once started in Marchhere's why, Jimmy Carter on the greatest challenges of the 21st century, This ancient Greek warship ruled the Mediterranean, How cosmic rays helped find a tunnel in Egypt's Great Pyramid, Who first rode horses? Air can be pushed back and forth between the two chambers making a bell-like sound called "chiming". Some mature males develop large, mole-like nodules called "bosses" over the skin of their necks, giving them a warty texture. [16], The modern walrus is mostly known from Arctic regions, but a substantial breeding population occurred on isolated Sable Island, 100 miles southeast of Nova Scotia and 500 miles due east of Portland, Maine, until the early Colonial period. The walrus (Odobenus rosmarus) is a large pinniped marine mammal with discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. Heres why each season begins twice. Melting sea ice means more Pacific walruses are resting on land, further from their feeding grounds. In the spring and fall, walruses congregate throughout the Bering Strait, reaching from the western coast of Alaska to the Gulf of Anadyr. [29] Tusks were once thought to be used to dig out prey from the seabed, but analyses of abrasion patterns on the tusks indicate they are dragged through the sediment while the upper edge of the snout is used for digging. Because of its distinctive appearance, great bulk, and immediately recognizable whiskers and tusks, the walrus also appears in the popular cultures of peoples with little direct experience with the animal, particularly in English children's literature.

Walruses use their tusks to haul themselves out of the water and onto the sea ice. Cows won't mate until they are about 8 years old, and these long development times give the walrus a very slow reproductive rate, so it is difficult to maintain stressed populations. Walruses have poor eyesight but are very curious. These tusks are not used for finding or piercing food, but for making breathing holes in sea ice, anchoring to the ice during sleep, and during competitions between males over females. A walrus's eyesight out of water is poor, but they can sense the others down below. [4] Male Atlantic walrus weigh an average of 900kg (2,000lb).
