These images are directly related to the latter two aspects of his research online. This brief respite after the initial chomping is what allows many human victims (but not all) to escape being eaten alive by the great white predator.

Preying on the weakest individuals also strengthens the gene pools of the prey species. Since the largest, strongest, and healthiest fish generally reproduce in greater numbers, the outcome is larger numbers of healthier fish.
