Interesting Animals - Sharks
Before they are born, sand tiger sharks eat their siblings until only one survives in each uterus.
(There is even a term for this, rather disgusting, phenomena: in utero cannibalization. Actually the female sand tiger shark has two uteri, so two pups can be born at one time. Sometimes nature is just downright icky!)
