To determine if the teeth of a Greenland shark could inflict clean-edged wounds such as those seen on Sable Island seal carcasses, a set of Greenland shark jaws was closed and twisted on a section of seal hide and blubber from an intact seal carcass found on the beach (i.e. a seal that died of natural causes other than shark attack). In this experiment, the band of lower teeth cut easily and cleanly through seal hide and blubber.
