Rob posted a link to a Discovery News story yesterday about shark embryos eating one another in the womb. Today, I read a second piece on this research that I have to share with you, for no other reason than this fantastic/horrific quote (and all the implications contained therein): “It’s so voracious that at least one scientist has been bitten by a sand tiger pup while unwisely sticking a finger in a pregnant female’s uterus.” Yes. Seriously.
