Polar Bears - Data, Pictures and Videos

[GreenGrolar]

Some food for thought: If belugas, narwhales, walruses, and bearded seals are classified as predators then the polar bear is the only bear recorded to hunt another predator larger than itself.

Old bull walruses sometimes turn carnivorous and feed on bearded seals as well as beluga and narwhale calves. Most of them hunt clams. Belugas and narwhales hunt fish and so do bearded seals. Given these sea mammals have skin thicker than land mammals and blubber to protect their vital organs, they are no easy prey for polar bears.

Male polar bears from Svalbard are slightly heavier than bearded seals while bull walruses can be two or three times the weight of a male polar bear. There is at least one video of a polar bear killing a beluga in the open waters.

Female bearded seals can weigh up to 800 pounds that is similar to in weight to a male polar bear from Svalbard and heavier than female polar bears. However, if female polar bears can kill belugas five times their weight, killing a bearded seal is no problem for them.

While bull walruses and even females are hard to kill even on land some polar bears have learned to throw rocks at them. Link below:
