Footage captured by Captain Hap Farrell, who owns a fishing vessel, shows a shark snatching away catches of the two groups in Cape Cod Bay. Coincidentally, they both happened the same day.
The first sighting was when a woman was reeling in her catch and the shark ripped it in half, leaving only its head attached to the fishing line.
In the second trip, the predator dramatically leapt out of water leaving almost nothing for the fisherman.
"It's not an unusual occurrence, but the fact that I had a video camera at the time, I was able to get the shot. You can't plan something like that," Mr Farrell told The Boston Globe.
Cape Cod Bay is a popular fishing spot. The area sees several fishing expeditions between the month of May and October. After the footage went viral, Mr Farrell wrote on Facebook that shark sightings are common in the area and happen at least once a day.
