Do Polar Bears Hibernate? A Look at What This Bear Family Animal Eats

The polar bear is a bear family animal and the largest land carnivore in the world, mainly living in sea areas with floating ice near the Arctic Ocean. Many animals have the habit of hibernation, so do polar bears hibernate? What do they like to eat?

1. What does a polar bear look like?

1. The polar bear is also called the white bear. Its head is relatively longer and its face smaller compared with the brown bear, its ears are small and round, its neck is slender, its feet are broad, its paws are covered with dense hair, its skin is black, and its fur is made of colorless, transparent hollow tubes, usually appearing white, but in summer it may turn pale yellow, brown or gray.

2. The polar bear is the largest land carnivore, reaching up to 2.8 m tall when standing upright as an adult, with a shoulder height of 1.6 m; males weigh 300-800 kg, females 150-400 kg, and in winter they can weigh more than 800 kg; a bear paw can be up to 25 cm wide, and a bear claw can exceed 10 cm.

3. The polar bear's eyesight and hearing are comparable to those of humans, but their sense of smell is extremely keen, able to detect scents within a 1 km radius or 1 m below snow and ice, 7 times that of dogs, and at a run their top speed can reach 60 km/h, 1.5 times that of the world 100 m champion.

4. The polar bear is an excellent swimmer, able to use its front paws as paddles to swim in the water, but it is not a marine animal; it merely lives by the sea and relies on marine food to survive; it is a mammal, the female's gestation period is 195-265 days, and each litter usually has two cubs, occasionally 1, 3 or 4.

2. Do polar bears hibernate?

Polar bears do hibernate.

1. In the severe winter, polar bears greatly reduce their outdoor activity and can go almost long periods without eating; at this time they look for a wind-sheltered place to lie down and sleep, their breathing rate drops, and they enter partial hibernation; polar bears only go without food or water for a relatively long period rather than the entire winter, and when hibernating they seem to sleep yet not sleep, so that they can wake immediately when they encounter an emergency.

2. Scientists have also suggested that polar bears may also undergo partial summer dormancy, that is, during the period in summer when floating ice is at its least, polar bears have difficulty finding food and may also be in a state of partial summer dormancy.

3. What do polar bears like to eat?

1. The polar bear is a true carnivore, with 98.5% of its food being meat; it mainly preys on seals, and also catches walruses, beluga whales, sea birds, fish and small mammals; it sometimes also scavenges carrion, and at the end of spring when summer approaches it will go to places by the sea to take seaweed washed ashore to supplement the minerals and vitamins its body needs; in summer it occasionally also eats a few berries or plant roots and stems.

2. Polar bears mainly use two modes to catch seals. The first is the sit-and-wait method, which is to first find a seal's breathing hole on the ice, then wait beside it and launch a sudden attack when the seal shows its head; if the seal is on the shore, they will hide somewhere the seal cannot see and then creep over stealthily to launch a fierce attack; the second is to dive directly under the ice and not attack until they get close to a seal on the shore.

3. A polar bear's stomach can hold 50-70 kg of food; after eating and drinking its fill, it will carefully clean its fur, removing all food residue and bloodstains; they will not hide unfinished food to eat later, and may even walk off after enjoying only the fat; for them, high-calorie fat is more important than meat, as it not only maintains the fat layer used for warmth but also stores energy for times when food is scarce.

Summary: The polar bear, also called the white bear, is the largest land carnivore, with an extremely keen sense of smell and great running speed, and is also an excellent swimmer. Polar bears do hibernate, but only partially, and scientists have also suggested that they may also undergo partial summer dormancy. The polar bear is a true carnivore, with 98.5% of its food being meat; it mainly preys on seals, and there are mainly two modes of catching them.
