The researcher joined Dr Kit Kovacs and Dr Christian Lydersen from the Norwegian Polar Institute, to tag Greenland sharks in the waters off Svarlbard.
It was initially thought that Greenland sharks simply fed on the carcasses of dead seals on the seafloor, but the team recently discovered evidence that they were consuming live seals.
Vincent Gallucci, a shark expert from the University of Washington, US, explained that Greenland sharks may not need "to get 100 percent of its mouth onto its prey" in order to eat it.

Equipped with a large torpedo-shaped nose and a bloodhound-like sense of smell, a Greenland shark might be able to follow a seal's scent--right into the seal's tunnel in the ice.

One of the factors that has threatened its survival is the fact that female Greenland sharks
do not breed until around 100 years old and individuals are thought to live for more than 150 years.
