Habitat and Ecology Walrus migrate with the moving ice floes, but never venture far from the coast as they feed in shallow waters. They can swim to a depth of around 100m to feed on molluscs and other invertebrates, but on average do not go much deeper than 20-30m.

On rare occasions they are killed by polar bears or killer whales. The walrus is valued by both the Inuit and commercial hunters for blubber, hide, and ivory tusks. Its numbers have been reduced by commercial operations.

The polar bear often hunts the walrus by rushing at beached aggregations and consuming the individuals crushed or wounded in the sudden exodus, typically younger or infirm animals. [87] The bears also isolate walruses when they overwinter and are unable to escape a charging bear due to inaccessible diving holes in the ice. [ 88 ]

Polar bears are forever linked to the Arctic sea ice, where they hunt their seal prey. The bears are found in five range states: the U.S. (Alaska), Canada, Russia, Greenland, and Norway (Svalbard). Scientists have divided them into 20 populations, some of …

Pacific walruses inhabit the Bering, Chukchi, and Laptev Seas. Atlantic walruses inhabit coastal areas of northeastern Canada and Greenland. Most walruses live where the air temperature is about -15° to +5°C (5° - 41°F). Walruses are generally found where the water is no more than 80 m (262 ft.) deep. They prefer a habitat with a gravelly bottom.

Majestic creature of the far north, the polar bear is the world’s largest terrestrial carnivore. Its Latin name, Ursus maritimus, means ‘sea bear’: an apt name for this amazing animal, which spends much of its life in, around, or on the water – predominantly on the sea ice.

An exception to this is threat walruses pose to polar bears. Polar bears and adult walruses are rivals, occasionally coming into contact while feeding on whale carcasses or in the process of killing seals. On land, a polar bear has the edge over …

The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).
