Which animals have the strongest bite?

12. Polar bear 1,200 PSI (84.3 kg/cm2)

The polar bear is one of the largest land predators and can reach 3 m (9.8 ft) in length and weigh one ton (2,000 lbs). Unlike most bears that feed on plants, polar bears are total meat-eaters. Their powerful jaws are necessary for the northern climate in order to cope with the thick-skinned food in the Arctic.
