Two heads are better than one, particularly if you’re a shark eager to slice your razor-sharp teeth through your next meal.

The 2012 movie 2-Headed Shark Attack (starring Carmen Electra, no less) may not have been worthy of Academy Awards, but based on recent news it’s chillingly prophetic.

According to the Journal of Fish Biology, scientists have recently stumbled upon a two-headed breed growing inside an egg. This particular baby embryo is twice the fun: two brains, four eyes, two mouths and twenty gills.

Recovered by a research vessel in the Mediterranean sea, this shark egg has now been split open and preserved for further research. The shark reportedly would not have survived if it had developed further.

The two-headed phenomenon is believed to occur in any mammal or fish with a spine.

“We see two-headed sharks occasionally,” George Burgess, director of the Florida program for shark research at the Florida Museum of Natural History, is quoted by National Geographic as saying.

“It’s an anomaly, caused by a genetic misfire. There are lots of different kinds of genetic misfires, and most don’t make it out of the womb.”

He added: “There’s a reason you don’t see a lot of sharks with two heads swimming around: they stand out like a sore thumb, so they get eaten. They would have trouble swimming and probably digesting food.”
