Polar bear, also known as white bear, sea bear or ice bear, is the largest land carnivore in the world. Although the grizzly bear can parry to its white relative, the polar bear is considered as extremely dangerous. Since this beast has no natural predators, it’s not so surprising, right?
How big is the polar bear?
This bear has a long neck, relatively small head, short, rounded ears, and a short tail. The male can grow up to 5,3 feet, and weighs from 900 to 1600 pounds. The shoulder length is between 7,2 to 8,2 feet. Did you know this bear isn’t actually white? The fur is translucent, and only appears white because it reflects visible light. Of course, under the skin is a layer of insulating fat.
Where does the polar bear live?
This marine mammal, (yes, you’ve read correctly) is found through the Arctic region. Its considered as marine because it spends most of its life on the sea ice. However, it is the only living marine with powerful, large limbs and feet that allow it to cover kilometres on foot and run on land.
We’ve mentioned on the beginning that this giant is extremely carnivorous. The favorite food of the polar bear is ringed but also the bearded seal. Yet, this opportunistic predator will even attack and eat beluga whales! Moreover, it will also consume dead fish and carcasses of stranded whales.
These bears mate in spring, and after 195 to 265 days the female gives birth to one to four cubs. Sadly, young bears can be killed by adult males. For this reason, mothers are extremely defensive when they are present. Because of the breeding between polar and grizzly bears, the hybrids of these two species also exist.
Did you know the polar bear can detect a seal in the water beneath a metre of compacted snow? That’s an extraordinary sense of smell!
