Recently CTV did a story on Canadian Researchers doing a study on the elusive Greenland shark in the Canadian Arctic. The team headed by Dr. Steven Campana fished through a five-foot diameter hole drilled through three feet of ice, and caught an average of two Greenland sharks each day.

On average, the sharks are between 2.5 and 3.5 metres in length, weighing in between 500 and 700 pounds. If the sharks were dead when they were hauled to the surface researchers would perform an autopsy. If they were still alive, they recorded their measurements, tagged them with satellite tracking devices and released them in order to learn more about their habits. CTV
