Hunting adult walruses is undoubtedly dangerous for polar bears. There have been isolated observations of walruses attacking polar bears in the water, though it is unusual. In the water, too, walruses generally react to polar bears as to predators – they fear and avoid them. Only rarely do they attack.
Among the most amazing of pinnipeds are the elephant seals. They are the biggest of pinnipeds – bigger even than walruses – there being a record of a giant male Southern elephant seal that was between 6.5 and 6.8 m long and weighed over 4000 kg (Carwardine 1995).
On occasion, polar bears kill beluga whales and young walruses. When other food is unavailable, polar bears will eat just about any animal they can get, including reindeer, small rodents, seabirds, waterfowl, fish, eggs, vegetation (including kelp), berries, and human garbage.
And though the walrus is an Arctic species and thus much harder to study in the wild than the elephant seals and sea lions that flop onto the beaches of Northern California, scientists are gathering evidence that Odobenus is the most cognitively and socially sophisticated of all pinnipeds.
Many residents of coastal communities in northern and western Alaska consume walrus and other marine mammals as part of subsistence hunting, or hunting for survival. This tradition is critical to their nutrition, food security and economic stability, according to the Alaska Department of Fish and Game.
Walruses are carnivores, but they aren't ferocious hunters. The walrus' favorite food is shellfish. According to the Smithsonian Institution's Arctic Study Center, a walrus can eat up to 4,000 clams in one feeding.
Fur seals often catch and eat penguins on the island. The incidents are the only time pinnipeds, the group that includes seals, fur seals and sea-lions, have been known to have sex with an animal from a different biological class, in this case a mammal trying to have sex with a bird.
The extraocular muscles of the walrus are well-developed. This and its lack of orbital roof allow it to protrude its eyes and see in both a frontal and dorsal direction.
Polar bears live in the Arctic, but not Antarctica. Down south in Antarctica you'll find penguins, seals, whales and all kinds of seabirds, but never polar bears. Even though the north and south polar regions both have lots of snow and ice, polar bears stick to the north.
Walruses are most known to attack people in boats, and can cause serious harm with their tusks or by capsizing the boat or kayak. A 1918 memoir notes a case in Spitzbergen where walruses capsized a boat, killing all aboard.
Diving. Walruses generally breathe at the surface for about one minute after every five to eight minutes of subsurface activity. They can stay submerged for as long as 10 minutes. A walrus's bottom-dwelling prey usually inhabit waters no more than about 80 m (262 ft.)
The main threats for penguins in water are leopard seals, fur seals, sea lions, sharks and killer whales. On land, foxes, snakes, lizards, dogs and some other animals are a threat for eggs and chicks in the case of species not in the Antarctic regions, like the Galapagos penguin among others.
Walrus TusksTheir 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.
While there is constant growth in tusks, there is also loss due to abrasion from contact with the mud, sand, and gravel of the sea floor while the animals are feeding. Fractures also occur, especially in adult males who have curved high divergent tusks.
Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs, bears, wolves, foxes, raccoons, badgers and mustelids. The Pinnipedia (seals, walruses and sea lions) are also assigned to this group.
Food Preferences & ResourcesWalruses prefer molluscs - mainly bivalves such as clams. They also eat many other kinds of benthic invertebrates including worms, gastropods, cephalopods, crustaceans, sea cucumbers, and other soft-bodied animals. Walruses may occasionally prey on fishes such as polar cod.
Because of their size and tusks, walruses only have two natural predators: orcas (killer whales) and polar bears.
The taste of rotten walrus (Igunak) is basically what your imagination supplies: picture a walrus, imagine what that smells like, then think about it rotting for 18 months and imagine what that smells like. Yup, you're spot on. Seal, however, tastes just like beef fillet.
Walruses. The walrus is an equal-opportunity sleeper. It can sleep anytime, anywhere, whether it's floating in the water, lying on the ground, or leaning on another walrus. Researchers have even noticed walruses resting in water while using their tusks to hang from ice floes.

Eat clams, oysters, and mussels like a walrusWalruses eat a huge variety of invertebrates, from crabs and snails to sea cucumbers and worms. Marine worms may be best left to the walruses, but one element of their diet is just as good for humans as it is for the ocean's health: clams, mussels, and oysters.
Though often mistaken for a mustache, the whiskers on a walrus are not hair, but incredibly sensitive vibrissae. Walruses have between 400 and 700 of these tactile organs lined up in 13 to 15 rows around the nose.
Walrus tusks just keep growingBoth male and female walruses have tusks that grow continuously throughout their lives.
: a large gregarious marine mammal (Odobenus rosmarus of the family Odobenidae) of arctic waters related to the seals that has limbs modified into webbed flippers, long ivory tusks, a tough wrinkled hide, stiff whiskers, and a thick layer of blubber.
Walruses live in one of the harshest environments on Earth. Not only do they dwell where temperatures are frigid -- they also spend the majority of their time in the water, where they lose body heat 27 times faster than they do on land.
Walruses produce sounds both above and below water. Walruses are among the most vocal of the pinnipeds. They produce growls, taps, knocks, grunts, barks, soft whistles, rasps, and clicks. These sounds are not produced by the vocal cords but originate from air sacs, which extend from the pharynx.
A group of walruses can also be called a 'herd' or a 'pod', but we like 'huddle' best. Walruses are most often found sunbathing on land or sea ice with hundreds of their companions.
Walruses are discontinuously distributed throughout arctic waters of the northern hemisphere. In Canada, the Atlantic walrus inhabits coastal areas in the northeastern Canadian Arctic. Walruses once occurred in the Atlantic provinces of Canada, but this population was hunted to extirpation by the late 18th century.
