Crocodiles have a bony braincase, which prevent brain crash in case they hit rocks

Crocodiles have a bony braincase, which prevent brain crash in case they hit rocks. Nonetheless, unlike other reptiles and mammals, its brain walls do not have postfrontal and supratemporal frames. Ironically, crocodiles cannot move their tongues in and out of the mouth. This is because; a special membrane holds it tightly in place hence; curtailing further movements. The sensory pores in the crocodile scales produce a secretory oily substance paramount in mud flushing during locomotion. (Huchzermeyer 12-13).

In order to crash the prey, crocodiles have very sharp teeth and powerful muscles for holding the prey tightly within the jaws. So far, research indicates that, the crocodile is an animal with the strongest bite, 340 atmospheres.
