What is the bite force of a bear in psi?

Answer 1

It's depending in which bear do you referring grizzly bear (a sub specie of the Brown bear) can exert a bite force of over 1,200 psi (over 540 kilograms) polar Bear can exert a bite force of over 440 psi (over 200 kg of force i give you this Result from the national geographic wild channel from the bio mechanical program Called ''i,predator'')

In my opinion polar bear can bite down with much stronger force like the grizzly or Slight harder because the polar bear(polar bears are larger in size in compression To the Grizzlies and have much stronger and thicker jaws compare to the grizzles And That's includes their sharper,longer canines) can bite through the skull of it's Prey which if some animal can do that she needs a lot of force to do so (like the Jaguar That can bite down with a force between 1,800 psi - 2,000 psi).

I,predator perhaps do an assumption to the polar bears bite force because they Couldn't (probably) measured the biteforce,they said the polar bears have one of The strongest and most deadliest jaws on the planet.
