A two-headed shark?

Yep... this is a fetal bull shark from the Gulf of Mexico, the first of its species found with two heads.  There have been two-headed sharks of other species, including a blue shark from the Indian Ocean in 2008.  Here's a publication on that one.   I only remember one other off the top of my head, from David Stead's book, I believe.  That was caught alive in Australia's Botany Bay several decades back.  This one is getting linked on the Internet to the Deepwater Horizon oil spill, but as its discoverer notes, there's no evidence of that.  It's just an extreme oddity, apparently.
