Polar bears are one of the largest bears—second only to Kodiak bears.
Large male bears are twice the size of adult tigers.
But where is the world’s largest polar bear?
Did scientists find the world’s largest polar bear in captivity or in a natural habitat?
Largest Polar Bear on Record – Largest Polar Bear
According to the Guinness Book of World Records, adult males weigh 385 to 410 kg (849 to 904 lb) in total body weight and a height of 133 cm (4 feet 4 inches).
The Beaufort Sea population is considered smaller with an estimated weight of 450 kg (992 lb).
Captive bears outnumber wild polar bears.
However, the largest polar bear ever seen was a male in northeastern Alaska.
Killed in 1960 in Kotzebue Sound—scientists wonder if there may be more polar bears out there.
The largest polar bear weighed 1,002 kilograms (2,209 pounds), twice the weight of male bears living today.
The world’s largest polar bear measured 3.39 meters (11 feet 1 inch) in length with a shoulder height of 122 to 160 cm (4 feet 0 inches to 5 feet 3 inches) .
Scientists say there may be fewer polar bears today than those found in the 1800s.
Global climate change is largely to blame.
As global temperatures rise, the Arctic sea ice melts, forcing polar bears to starve for months at a time.
It is very difficult for polar bears to find seals as their first meal.
Climate change has adversely affected the entire life of the polar bear.

Polar bears (scientific name: Ursus maritimus) are one of the most beautiful and terrifying animals in the world.
These giant predators are well-adapted to living in the harsh Arctic environment, with thick fur, webbed feet, and an amazing sense of smell that allows them to find food from afar.

Information about the polar bear
1. The polar bear is the largest bear in the world
The polar bear is the largest bear and the largest hypercarnivorous mammal (see note 1) in the world.
The polar bear is the largest bear on earth.
On average, Pigs (adult males) weigh around 350-700 kg (772–1,543 lb), while sows (adult females) are half that size.
The largest brown bear, the Kodiak is probably the second: males (boars) average 360 to 635 kg (794 to 1,400 lb), females (sows) from 225 to 315 kg (496 to 694 lb).
The height at the shoulder of an adult polar bear is 122 to 160 cm (4 feet to 5 feet 3 inches).
Large male specimens can easily stand 3+ meters tall (over 10 feet) on their hind legs.
An adult Kodiak bear (male) is 244 cm (8 feet) long and 133 cm (4 feet 4 inches) tall at the shoulder.
A large male Kodiak bear can be up to 1.5 meters (4.9 feet) tall at the shoulder when standing on all fours.

Very few polar bears are content to kill humans unless provoked.
However, due to a lack of human interaction in the past, hungry polar bears are unpredictable, fearless of humans, and have been known to kill and sometimes cannibalize humans.
Many attacks by brown bears are the result of startling the animal, not the polar bear.

The polar bear is a good swimmer and can swim for days.
Their front feet are large, flat, paddle-like, and helpful.
They use it to paddle through the water and hold their hind legs like a rudder.
At one time, researchers tracked 52 whales in the southern Beaufort Sea off Alaska with GPS system collars; no pigs were included in the study because males have too thick necks for GPS collars.
Fifty distance swimmers were recorded; the longest is 354 km (220 miles), and the average is 155 km (96 miles).
Ten of the sows had cubs swimming with them, and after a year, six cubs survived.
They are not very fast swimmers, however, they swim well at 10 km/h (6 mph).
For example, they are not fast enough to catch seals in open water.
Polar bears have black skin to absorb the sun’s heat, but their fur is white to blend in with their surroundings.
7. Their fur is not clean
This helps the bears blend in with their surroundings.
Before molting, the oil accumulated in their fur from the seals that they eat causes them to appear yellow.
A polar bear can smell its food from a kilometer away.
They can see a seal in the water under a meter of packed snow.
Polar bears have a very good smell.
8. Polar bears don’t hibernate

But they can eat a variety of wild foods, including muskox (Ovibos moschatus), reindeer (Rangifer tarandus), fish, birds, eggs, mice, crabs, and other crustaceans. , and … (oh!) other polar bears.
The polar bear’s metabolism is specialized to get a lot of fat from marine mammals, and it can’t get enough caloric from land food.
Polar-polar hybrids exist
In 2006, DNA testing of a unique-looking bear shot near Sachs Harbour, Northwest Territories on Banks Island in the Canadian Arctic confirmed that polar bears can interbreed with brown bears. produce good polar-polar hybrids – and name them. the grolar bear, pizzly bear, or nanulak.
Polar-grizzly bears of the wild variety have been reported and shot in the past, but DNA testing is not available.
According to the WWF, the cubs are usually born from polar bear mothers and raised as polar bears.

Polar bears are apex predators, at the top of the food chain.
However, they may be vulnerable to predation by orcas (Orcinus orca – killer whales) while swimming.
However, in 2008, researchers found the jawbone of a polar bear cub in the stomach of a Greenland shark.
Except for females with cubs, polar bears are solitary animals.
However, they are often seen playing together for hours at a time and sleeping in each other’s arms, and polar bear wildlife expert Nikita Ovsianikov said, older men are “good friends”.
Polar bear cubs are born blind, covered in light fur, and weigh less than 0.9 kg (2.0 lb).
On average, each litter has two cubs.
Mothers give birth between November and February, ensuring that polar bear cubs are born to healthy mothers when they have the highest chance of survival.
On October 11, 2011, a family of polar bears were captured at the Toronto Zoo. The lifespan of polar bears in the wild is 18-20 years.

Polar bears were one of the first species to become extinct due to anthropogenic climate change.
Polar bears were one of the first species to become extinct due to anthropogenic climate change.
They rely on sea ice to cover large areas in search of food.
A longer melting period due to climate change causes sea ice to form later and break up earlier in the year, restricting the polar bears’ food range.
This is especially true for pregnant females, who need to build fat stores to survive during calving and nursing.
Other risks include pollution in the form of toxic pollutants, collisions with shipping, oil and gas exploration and development, hunting, and human-bear interactions including harvesting and stress. perhaps from watching polar bears.
Organizations like the WWF are working hard to save space for polar bears.
You can help them by adopting a polar bear and supporting their research and conservation projects.
You can also check out the polar bear tracker to see which polar bears they are tracking and what they are studying.
If an animal’s diet is more than 70% meat it is called a hypercarnivore.
