A closer look
Nothing screams apex predator quite like intentionally consuming solid rocks to violently override natural buoyancy. Crocodiles literally swallow massive gastroliths, letting the incredibly heavy stones aggressively sit inside their highly acidic stomachs. The extra weight firmly allows them to dive drastically deeper and quietly lurk completely underwater for hours. As a deeply terrifying bonus, the rocks intensely grind up the unchewed bones of their totally doomed prey.
