Most of the shark experts contacted think that the bear was probably dead when the shark found it. Even a young bear of two or three years could be a ferocious opponent for a Greenland shark, which can weigh more than a ton.

According to Steve Campana, head of the shark research laboratory at the Canadian Department of Fisheries and Oceans, it looks like more a scavenge than an attack. He said he never heard about sharks attacking polar bears before

Knowing if sharks can attack polar bears is a "million dollars question" he added.
