Although the shark's bark seems soft, looking under a microscope shows that it has toothed scales. It has long been considered that this skin protects the shark against predators and parasites and helps swim faster.
However, it also helps newborn sharks fragment large prey, as in marriages they do not have enough strength. He holds the prey with his mouth and with a quick movement, rubbing on the scales of the tail, gets fragments that can be swallowed.
