Gulf of Greenland?

  Roughly two days ago, scientists on board the boat RV Apalachee found a Greenland shark in the Gulf of Mexico. Greenland sharks only live in the Arctic circle and, until now, that was common knowledge. They are the only type of shark that can live underneath the polar ice caps. The specimen was twelve foot (just under four metres) long.
  The biologists and scientists on board the vessel were studying the effects of a three-year-old oil spill on marine life and found as many as forty-four species of shark on their journey-all alive- throughout the Gulf of Mexico.
  Chip Cotton, a Florida State University researcher and part of the expedition, said, quote: "No way is this the only Greenland shark in the Gulf." Which is a good sign for the shark species.

Greenland sharks were never found away from Greenland...
Until now.
