How often do polar bears have to eat?
A polar bear can devour up to 150 pounds of food in one sitting but must capture a seal once every five to six days to maintain its body weight.
What percent of the time do polar bears catch their prey?
2 percent
Polar bears succeed in catching their prey in only 2 percent of their attempts, the National Zoo says.
How long can polar bears go without food?
seven to 10 days
They can go days without eating If a polar bear doesn’t eat for seven to 10 days, it can slow its metabolism until it finds its next meal. They survive off of fat reserves from their diet, which consists mostly of ringed and bearded seals.
How often does a polar bear catch a seal?
By the fall, the young seals are older and wiser, and polar bears are not able to catch as many. “It’s thought that bears might catch a couple per month in the fall, compared to five to 10 per month in the spring and early summer,” Pagano said.
Why are polar bears failing to catch enough prey?
Polar bears could be failing to hunt enough seals to meet their energy demands, new research suggests. A study tracking the behaviour of nine female bears from 2014 to 2016 over the Beaufort Sea found that some of the animals exerted so much energy during the hunting season that they lost up to 10% of their body mass in an 8-11 day period.
How much food does a polar bear eat in a day?
How Much Do Polar Bears Eat In A Day? On average, a polar bear could eat about 30 kilos of food a day. Newborn polar bears eat much less and would be able to eat about 1 kilo a day.
How are polar bears at the top of the food chain?
Hunting and Predators. Polar bears rely sea ice to find and catch most of their prey. Polar bears are at the top of the food chain in the Arctic. Aside from humans, the only threat to polar bears are other polar bears.
How often do polar bears attack the seals?
They surface about every five to fifteen minutes at one of the holes or use air pockets trapped under the ice when available. Polar bears attack by waiting for seals to breathe at the openings.
What kind of prey do polar bears eat?
The principal prey of Polar bears is the ringed seal, which the bears hunt from the ice surface. However, sea ice cover in the Arctic is in decline – by as much as 14% per decade for September. This may be forcing some polar bears to travel further in order to find their prey, the authors of the new research say.

Where do polar bears spend most of their time?
Polar bears depend on the sea ice, which forms above the open waters where their seal prey lives. They will spend time on land when sea ice is not available (and most pregnant polar bear females make their dens on shore near the coast). Polar bears are excellent swimmers, and they travel long distances between shore and the sea ice if necessary.
