Walrus were once hunted, causing their numbers to drop, but since most hunting has stopped, their numbers have recovered and they’re not endangered.

Males aggregate in the water around ice-bound groups of estrous females and engage in competitive vocal displays. Check out Walrus DE6368 #999B9B, one of the 2006 paint colors from Dunn-Edwards.

Its numbers have been reduced by commercial operations. [45][46] There were roughly 200,000 Pacific walruses in 1990. The population of walruses dropped rapidly all around the Arctic region. Walrus, huge, seal-like mammal with long tusks (upper canine teeth) found in the Arctic seas. Browse our extensive collection of zoological career infobooks including animal training, animal rescue and rehabilitation and zoo careers. The first three to four months are spent with the blastula in suspended development before it implants itself in the uterus.

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.

This species is subdivided into two subspecies:[2] the Atlantic walrus (O. r. rosmarus), which lives in the Atlantic Ocean, and the Pacific walrus (O. r. divergens), which lives in the Pacific Ocean. The walrus has an air sac under its throat which acts like a flotation bubble and allows it to bob vertically in the water while sleeping.
A 3-4 week clerkship for veterinary students wanting to augment their knowledge and experience in non-domestic animal medicine. [4] They rut from January through April, decreasing their food intake dramatically. Calves are grey to brown in color and weigh about 99-165 pounds at birth. Jefferson, T.J. Leatherwood, S. and M.A. [47][48], The much smaller population of Atlantic walruses ranges from the Canadian Arctic, across Greenland, Svalbard, and the western part of Arctic Russia. [80] The sustainability of these levels of harvest is difficult to determine given uncertain population estimates and parameters such as fecundity and mortality. This and its lack of orbital roof allow it to protrude its eyes and see in both a frontal and dorsal direction. [83][84] Analysis of trends in ice cover published in 2012 indicate that Pacific walrus populations are likely to continue to decline for the foreseeable future, and shift further north, but that careful conservation management might be able to limit these effects. Sign Me Up. [63][64] Rarely, incidents of walruses preying on seabirds, particularly the Brünnich's guillemot (Uria lomvia), have been documented. While its size is intimidating it is actually a carnivore. Limits on commercial hunting allowed the population to increase to a peak in the 1970s-1980s, but subsequently, walrus numbers have again declined.

There are two subspecies: the Atlantic walrus (Odobenus rosmarus rosmarus) and the Pacific walrus (O. rosmarus divergens).

There can be 400 to 700 vibrissae in 13 to 15 rows reaching 30 cm (12 in) in length, though in the wild they are often worn to much shorter lengths due to constant use in foraging. Take a closer look at these encyclopedia books including information about animal habitats, behavior, and scientific classification.

O. rosmarus laptevi (debated). This species is subdivided into two subspecies: the Atlantic walrus (O. r. rosmarus), which lives in the Atlantic Ocean, and the Pacific walrus (O. r. divergens), which lives in the Pacific Ocean. The walrus is the only living species in the family Odobenidae and genus Odobenus. San Francisco: Sierra Club Books, 1992. 1. While some outsized Pacific males can weigh as much as 2,000 kg (4,400 lb), most weigh between 800 and 1,700 kg (1,800 and 3,700 lb). Their name, Odobenus rosmarus, means 'one that walks with teeth'. Color theory encompasses a multitude of definitions, concepts and design applications - enough to fill several encyclopedias. The Norwegian manuscript Konungsskuggsja, thought to date from around AD 1240, refers to the walrus as "rosmhvalr" in Iceland and "rostungr" in Greenland (walruses were by now extinct in Iceland and Norway, while the word evolved in Greenland). A walrus is a marine mammal, the only species of the family Odobenidae, which is one of the three pinniped families. Walruses have lots of things similar to true seals and eared seals. Walrus Worksheets. and S. Stephen. Walruses are very distinctive having a large, robust, fusiform body that is usually reddish-brown in color. Download free teacher guides to keep students learning in a hands-on way: includes vocabulary, classroom activities, goals and objectives. Several place names in Iceland, Greenland and Norway may originate from walrus sites: Hvalfjord, Hvallatrar and Hvalsnes to name some, all being typical walrus breeding grounds. Nowak, Ronald M. (ed.). The most famous thing about walruses are their tusks. This more widely separates lactating females from their calves, increasing nutritional stress for the young and lower reproductive rates. Because skin blood vessels constrict in cold water, the walrus can appear almost white when swimming. The walrus is valued by both the Inuit and commercial hunters for blubber, hide, and ivory tusks. Killer whales regularly attack walruses, although walruses are believed to have successfully defended themselves via counterattack against the larger cetacean. [85], Currently, two of the three walrus subspecies are listed as "least-concern" by the IUCN, while the third is "data deficient". [17] The Atlantic subspecies weighs about 10–20% less than the Pacific subspecies.

Smaller numbers of males summer in the Gulf of Anadyr on the southern coast of the Siberian Chukchi Peninsula, and in Bristol Bay off the southern coast of Alaska, west of the Alaska Peninsula. The distinctive 12th-century Lewis Chessmen from northern Europe are carved from walrus ivory. Blubber also streamlines the body and functions as an excess energy reserve.
