Many sharks can push their jaws forward when biting a fish 🦈 the jaw is normally pulled slightly back under the head, when the shark bites muscles push the jaw outward.
Some species can move their jaws forward several centimeters in a split second and as it is made of cartilage, sharks can move their jaws quickly in the water.
They can open their mouths very wide because their jaw is not rigidly attached to the skull either and even if cartilage is a flexible material lighter than bone, the jaw is strong enough for powerful bites.
