When fearing a predator or human activity (such as a low-flying aircraft), walruses may stampede and trample calves and yearlings. [55] This population was nearly eradicated by commercial harvest; their current numbers, though difficult to estimate, probably remain below 20,000.

As more walruses haul out on land instead of sea ice, nearshore prey populations will be subjected to greater predation pressure. The walrus has a process of delayed implantation, which means the embryo does not start to develop until it has been in the womb for about 4 months. Blubber not only provides insulationbut can help make the walrus more streamlined in the water and also provides an energy source during times when food is scarce. Iritis: this is inflammation of the iris, which is the colored part of the eye. Daughters or other female relatives, may join the new mom and can be very protective and maternal. In the Pacific, adult male walruses reach about 3.6 m in length and weigh 880-1,557 kg; adult females are about 3 m and 580-1,039 kg. 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. In October 2017, the Center for Biological Diversity announced they would sue the U.S. Their tusks, oil, skin, and meat were so sought after in the 18th and 19th centuries that the walrus was hunted to extinction in the Gulf of St. Lawrence and around Sable Island, off the coast of Nova Scotia. [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. Most of the underwater propulsion comes from the rear flippers, with the front flippers kept close to the sides and used only occasionally for steering and extra boost. The blubber layer beneath is up to 15cm (6in) thick. [104], The "walrus" in the cryptic Beatles song "I Am the Walrus" is a reference to the Lewis Carroll poem. However, redness of the eye sometimes can signal a more serious eye condition or disease, such as uveitis or glaucoma. These animals can sniff it out.

Walruses' scientific name (Odobenus) translates from Latin into "tooth walking sea horse". This makes sure that the mother has the calf at a time when she has the necessary nutrition and energy, and that the calf is born during favorable environmental conditions. [10], The compound Odobenus comes from odous (Greek for 'teeth') and baino (Greek for 'walk'), based on observations of walruses using their tusks to pull themselves out of the water. In 1909, a walrus hide weighing 500kg (1,100lb) was collected from an enormous bull in Franz Josef Land, while in August 1910, Jack Woodson shot a 4.9-metre-long (16ft) walrus, harvesting its 450kg (1,000lb) hide. Today, it is unknown whether more concentrated foraging by walruses will change or deplete nearshore prey communities, or if walrus energetics will be affected if prey do become less abundant. Most pinnipeds cruise at speeds around 5 to 15 knots, though sea lions sometimes reach bursts up . Some describe them as aggressive monsters because of the sound and smell of their farts and the sight of their clear snot. Walrus skin becomes pink-red rather than the usual grey-brown when sun-bathing on the ice. They run on all fours like a dog. Kennedy, Jennifer.

Red eyes occur when the blood vessels on the surface of the eye expand. The vibrissae which are placed around the side of the snout (their 'whiskers') are longer than the vibrissae in the center. [16] These dates coincide with the hypothesis derived from fossils that the walrus evolved from a tropical or subtropical ancestor that became isolated in the Atlantic Ocean and gradually adapted to colder conditions in the Arctic. [40], Commercial harvesting reduced the population of the Pacific walrus to between 50,000 and 100,000 in the 1950s-1960s. This more widely separates lactating females from their calves, increasing nutritional stress for the young and lower reproductive rates. Manage Settings Both male and female walruses have tusks, although a male's can grow to 3 feet in length, while a female's tusks grow to about 2 1/2 feet. [15] The key distinguishing feature was the development of a squirt/suction feeding mechanism; tusks are a later feature specific to Odobeninae, of which the modern walrus is the last remaining (relict) species. They use their tusks to haul themselves ashore and to move around land. The problem the melting ice cap poses for walruses is that the distance between the sea ice where they live for much of the year, and the coastlines where they feed is increasing as the ice margins recede.

The maximal number of teeth is 38 with dentition formula: 3.1.4.23.1.3.2, but over half of the teeth are rudimentary and occur with less than 50% frequency, such that a typical dentition includes only 18 teeth 1.1.3.00.1.3.0[4], Surrounding the tusks is a broad mat of stiff bristles ("mystacial vibrissae"), giving the walrus a characteristic whiskered appearance. Their tusks, which are found on both males and females, can extend to about three feet, and are, in fact, large canine teeth, which grow throughout their lives. Tusks are also used to form and maintain holes in the ice and aid the walrus in climbing out of water onto ice. They have 18 teeth, two of which are canine teeth that grow to form their long tusks. These were the first haul-outs of this size seen, and it appears the problem is only getting worse. Walruses live in huge herds of sometimes several thousand individuals, but these herds are separated by sex, and only come together once a year to mate. the main use of the tusks is to help the walrus haul itself up out of the water. Walruses are bottom feeders who forage for invertebrates in the relatively shallow waters off the coasts. Its a pretty slick move, and when you see a mass like that wrenching itself from the ocean in a single motion you realize the simple utility of the incredible tusks.
