In the video, the man kneels before a crocodile which is lying motionless with its jaw wide open.
The crocodile remains still as the zookeeper does his routine with two wooden sticks. He waves the stick around the beast’s open mouth and fleetingly pokes it inside.
Then the man does something that eventually almost costs him his life: He shoves his complete head inside the stationary crocodile’s mouth.
The man screams as the audience, shocked, watches. He is left on the ground as the crocodile glides back into the water.
Prior to the deed, the man showed the crowd his previous wounds, including a missing finger.
Most notable, perhaps, is that the animal could have easily killed the man or snapped his neck, if he had wanted to do so.
But the enormous reptile, it seems, was merely playing around with the man.
Consider the work of paleo biologist Gregory M. Erickson, who put the crocodile’s bite to the test. He and his co-workers gauged the bites all 23 living species of crocodile. Those with the most bang to their bite, the saltwater variety, slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force.
And, to paint a clearer depiction of how fortunate this man is to be alive, 235 kg (520 pounds) or 2,300 newtons of force is required to crush a human skull. That’s a far cry from 16,460.
