Kodiak Bear
credit to @jamesonbevans The information attached says that it is a World Record Kodiak Bear 31 inch skull, I asked Jameson Lance Bevans if he knew all its measurements but sadly he never responded. It says that it is in Alaska Airlines - Ted Stevens - Anchorage  *This image is copyright of its original author

Granted, that's assuming the computer models are right, but even so, it does seem a bit odd. Similarly, while they do have less premolar teeth than many other bears (a feature they share with cats, for example), the teeth overall seem somewhat weaker than one would expect for a purely carnivorous animal. One reason may be what the polar bears are eating. Their diet consists almost entirely of seals, which, unlike the antelopes eaten by lions, have a lot of soft blubber. If their food is less tough than the meat favoured by other hypercarnivores, they don't need such strong jaws, and the evolutionary change required to adapt to that diet may be less than it first appears. It may also help that, while animals like leopards and wolves regularly take down prey larger than themselves, polar bears obviously don't. Seals just don't get that big! There is, however, a clear downside to this rapid evolution and specialization.
*I would love to see some class-A information being posted on this topic - like from Peter, Guate Gojira, Tigerluver, Apollo, Grizzly Claws and others who can add some real quality information.
About bear bite-force. Remember that the bears who have ( pound-for-pound ) the strongest bite are primarily vegetarian - the giant panda, sun bear, and ( if I remember correctly ) the Andean bear. The grizzly ( pound-for-pound ) comes in at fourth place. The sloth bear, which feeds on brood insects and soft fruits, comes in at last. Because of his size, the grizzly has the strongest bite of living bears.
I wonder if the European cave bear, Ursus spelaeus, has ever been studied for bite force?

Among large carnivores and some herbivores or other omnivores, the bears do not have the strongest bit force; but a powerful bite never-the-less. A grizzly often kills with a bite to the spine of his prey or opponent.
 
Found this one today. I don't know how legit it is, but I love the Grizzly's claw, it's massive.
