The Iceland catshark species, including this fish caught during the study period, is among several sharks recently found in Greenland waters for the first time.
The small shark has been found in other oceans at depths of between 2,645 to 4,625 feet (800 and 1,410 meters), where it feeds on fish, marine worms, and crustaceans such as lobster and crabs.
The recent discoveries of deep-dwelling species, such as the catshark, are probably due largely to an increase in deep-sea fishing around Greenland—and a resulting boom in odd, accidental catches—the survey team says.
Five of the 38 new-to-Greenland fish species are relatively shallow dwellers, though, and were likely lured into their new habitats by warming seas, the team says.
