Given the alter in climate, with ice breaking up in parts this kind of as the Hudson Bay before than it utilized to, polar bears are exploiting food stuff resources this kind of as snow geese and eggs, and plants this sort of as lyme grass in elevated quantities. The polar bear's metabolism is specialized to involve big amounts of fat from maritime mammals, and it are unable to derive sufficient caloric intake from terrestrial foodstuff. During these four months, the pregnant female eats prodigious quantities of meals, attaining at least two hundred kg (440 lb) and normally extra than doubling her physique weight. Adult male bearded seals, at 350 to 500 kg (770 to 1,100 lb) are as well massive for a female bear to overtake, and so are prospective prey only for experienced male bears. Large males also sometimes endeavor to hunt and destroy even more substantial prey products.
They will even attack adult walruses when their diving holes have frozen over or intercept them prior to they can get again to the diving hole in the ice. The bearded seal, on the other hand, can be approximately the very same dimensions as the bear by itself, averaging 270 kg (600 lb). Although polar bears are extraordinarily potent, its most important prey species, the ringed seal, is significantly scaled-down than by itself, and a lot of of the seals hunted are pups instead than adults. They also in sites prey heavily on the harp seal (Pagophilus groenlandicus), the harbour seal (Phoca vitulina), or the hooded seal (Cystophora cristata). Subadults might also be pressured to take a fifty percent-eaten carcass if they destroy a seal but can not protect it from bigger polar bears.

Polar bears hunt largely at the interface among ice, h2o, and air they only almost never catch seals on land or in open up water. They even now handle to eat some seals, but they are foods-deprived in summertime as only marine mammal carcasses are an essential different with no sea ice, especially carcasses of the beluga whale.
Most polar bears elsewhere will under no circumstances have accessibility to these options, apart from for the marine mammal carcasses that are critical anywhere they arise. For subadult bears, which are independent of their mom but have not yet obtained enough practical experience and physique measurement to correctly hunt seals, scavenging the carcasses from other bears' kills is an essential supply of nutrition. Bacterial leptospirosis and Morbillivirus have been recorded. Since an assault on a walrus tends to be an incredibly protracted and exhausting venture, bears have been acknowledged to back down from the assault right after producing the first harm to the walrus. A polar bear may well cost a team of walruses, with the goal of separating a young, infirm, or hurt walrus from the pod. Among youthful males in specific, play-preventing may well be a indicates of working towards for major opposition through mating seasons later in everyday living. Partners remain jointly and mate consistently for an total week the mating ritual induces ovulation in the feminine.
There was an earlier arcade recreation symbolizing feminine people, Exidy's arcade activity Score (1977), but no screenshots of the activity are acknowledged to be readily available.

They were being also diving to feed on blue mussels and other underwater foods resources like the environmentally friendly sea urchin. Unlike brown and black bears, polar bears are capable of fasting for up to various months in the course of late summer time and early tumble, when they are unable to hunt for seals because the sea is unfrozen. The evolutionary stress of polar bear predation on seals almost certainly accounts for some substantial distinctions between Arctic and Antarctic seals. The polar bear is the most carnivorous member of the bear household, and throughout most of its vary, its diet program principally consists of ringed (Pusa hispida) and bearded seals (Erignathus barbatus).
