    Sharks eat their siblings… in the womb
    It's not easy being a baby shark. For one thing, your siblings will try to eat you.
    Biologists have known for decades that shark fetuses will cannibalize each other in the womb — no brotherly love here. Shark mothers can store up sperm from multiple mating events and fertilize their eggs over time, so they frequently have a womb full of half-siblings. In sand tiger sharks (Carcharias taurus), the babies of one father tend to dominate those from another father over time, a way that males apparently compete to father the most offspring well after mating occurs.
    Baby sharks will even swim from one uterus to another (sharks have two uteruses) in search of a meal. A 2018 study found that tawny nurse shark babies wiggle between uteruses and sometimes even poke their heads out of their mother's cervix before they're ready to be born.

        That is more acceptable since that is natural then what humans to to them which is unnatural which is to cut off their fins, for shark fin soup that the Chinks make, then to throw them back overboard which lets them suffer and die on the bottom of the ocean since they are unable to swim anymore.
        This happens to millions of sharks a year putting their species in danger.
        And then of course there is the ongoing fishing and murdering of them as well.
