Crocodiles have the strongest bite

How strong is a crocodile’s bite?

A crocodile has the strongest bite of any known creature, producing a force of around 5,000 pounds per square inch. The muscles that control this bite down have evolved and developed to be extraordinarily strong, and alongside relative speed over short distances on land and the immensely sharp teeth that crocodiles prominently display, this forms an immense weapon for the crocodiles to successfully hunt within a competitive environment.

However, although the jaw muscles used to snap the jaw shut are well developed, the muscles used to open the jaw are considerably weaker, so much so that if the jaw is taped shut or a large rubber band is put around it, the muscles are not strong enough to push up against the force created by these.
