Do Polar Bears Hibernate?


Do Polar Bears Hibernate?



Do Polar bears hibernate-It's astonishing but unlike other bears, they don't hibernate, yet females do go into a latent(inactive) state during pregnancy.

The priority of a female polar bear, after mating in the spring is to consume a lot of nutrition.

Amid the winters, she goes into a latent state & gives birth to an offspring in the same state.



Hibernation is a phase of dormancy and metabolic inactivity & usually perceived amid the winters.
Science is yet trying to conceive on how to describe hibernation appropriately — as different creatures perform it in somewhat different means.

Amid hibernation body temperature & metabolism drops followed by a significant drop in breathing & pulse rate.

Do Polar Bears Hibernate?

Researchers when compared the genetic coding in polar bears & other bears discovered that the genetic coding which controls the production of nitric oxide is seemed to be more abundant in polar bears.

Researchers say the nitric oxide plays a vital role in metabolism & generation of heat within the body; therefore the genetic orientation is essential.

The nitric oxide may hinder energy production at high levels & boost heat generation.

What do polar bears eat?


They are voracious eaters, unlike other bear species they are entirely carnivorous. Primarily they feed on bearded seals & ringed seals.

The fatty part(blubber) of the seal tempts the polar bear.

But when the food is scarce, they become very opportunistic & not even hesitate to go after small animals, birds & carcasses.

If there is a shortage of their primary food, they start feeding on the carcasses. Polar bears quite occasionally kill young walruses and beluga whales.

Polar bears don't have sufficient time to build up the required fat reserves as the ice season is getting shorter because of global warming.

Polar bear adaptations


They are robust swimmers. They pedal in water through their large front paws, the back legs for the most part trail back.

They have very thick fur which covers the whole body and work as a perfect insulator. In this frosty habitat of theirs, cold is not a problem, but overheating is.

They usually abstain from running as it cause overheating.

Polar bears prefer a fat-rich diet. Most of the creatures could endure such a fat-rich diet. Most of the time they eat just the fat of the seal, leaving the carcass.

A polar bear has the thickest fur coat compared to others of same species. There are two sorts of hairs, short delicate thick internal hairs, and longer stiffer external hairs.

The coat normally seems to be absolutely white, however, has a light yellow tint to it which turns out to be frequently more in older animals. 

Are there polar bears in Alaska?


Polar bears can be found in Alaska in the springs but only near Arctic coastlines. In winters, they aggregate in the southernmost tip of St. Lawrence, St. Mathew Island and Kuskokwim Delta.
