'Resurrected' Shark Species Found Dwelling Deep in the Atlantic

Scientists have discovered a new species of shark cruising the Atlantic Ocean.

The Atlantic sixgill shark is a deep-sea dweller that gives birth to sweet-faced pups. It was long thought to be part of a global species of sixgill shark known as Hexanchus nakamurai, but new genetic evidence reveals that it's a separate species. Researchers have dubbed the newly discovered shark Hexanchus vitulus.

"We showed that the sixgills in the Atlantic are actually very different from the ones in the Indian and Pacific Oceans on a molecular level, to the point where it is obvious that they're a different species even though they look very similar to the naked eye," Toby Daly-Engel, a shark scientist at the Florida Institute of Technology, said in a statement.[On the Brink: A Gallery of Wild Sharks]
