Polar bears rely on raw power when trying to kill their prey, and will employ bites and paw swipes. [95] They have the strength to pull a mid-sized seal out of the water or haul a beluga carcass for quite some distance. [113] Polar bears only occasionally store food for later—burying it under snow—and only in the short term. [114]
Solitary predator: a polar bear feeds on a bearded seal it has killed. Social predators: meat ants cooperate to feed on a cicada far larger than themselves.. Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey.
Ringed seals are both predators and prey. A predator to zooplankton and fish, the ringed seal is considered a primary consumer as well as a secondary consumer. But the tertiary consumer, or top predator, in the Arctic is the polar bear, feeding mostly on seals, including the ringed seal.
Running away from a charging polar bear is – perhaps counterintuitively - dangerous. A bear's instinct is to chase prey and polar bears can run at 25mph (40kmph). Key advice: Be vigilant and ...
As an example of related species with differing diets, even though they diverged only 150,000 years ago, [7] the polar bear is the most highly carnivorous bear (more than 90% of its diet is meat) while the grizzly bear is one of the least carnivorous in many locales, with less than 10% of its diet being meat.

Polar bears rely on seals and fish as their primary food source. While the bears can hunt land mammals such as caribou and fox, they can survive off of land prey for only approximately 6 months. Without the abundance of sea ice, polar bears cannot access seals and fish and, thus, can starve. [17]
Most reported cases of man-eaters have involved lions, tigers, leopards, polar bears, and large crocodilians. However, they are not the only predators that will attack humans if given the chance; a wide variety of species have also been known to adopt humans as usual prey, including various bears, spotted and striped hyenas, and Komodo dragons.
The key danger for polar bears posed by the effects of climate change is malnutrition or starvation due to habitat loss.Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall.
