A great white shark was spotted circling a fisherman's boat near Cape Cod, Massachusetts, before attempting to destroy a part of the boat. Instagram shared images show the shark swimming around a whale's carcass before heading to the boat. Fishermen can be heard saying, "He's getting straight to the boat," as the great white approaches to try to bite the boat before stopping the attempt and turning.
Fisherman Matt Taylor, who told CBS Boston that he was crawfish on Cape Cod Bay with his friends when he filmed the video, captioned the video: "The most epic things I've ever seen in the water.
"Great white sharks up to 20 feet long, feeding on a dead whale in Cape Cod Bay."
Cape Cod is not new to shark sightings, and last year the area panicked after a swimmer died after being bitten while swimming in Newcomb Hollow Beach.
Arthur Medici, 26, is believed to have been the first victim of a shark attack off the coast of Massachusetts in over 80 years.

Shark populations foreign to the US east coast city have increased in recent years, with scientists suggesting that the growing number of potential prey was the main cause of the shark boom.
The increasing risk of attacks has led Bay towns to adopt new technologies to alert lifeguards when an identified shark comes near the beach.
Massachusetts shark researcher Greg Skomal began tagging sharks near Cape Cod in 2015, but warned that the number of animals he recorded in his records is a small part of the actual number of sharks in local waters.
Speaking to NPR, Mr. Skomal said: "We know at least 300 people are visiting Cape Cod, but we can definitely say that this is not the real estimate – it will be much more than that.

He added: "I am absolutely concerned and want to be as prepared as possible.
"It's a wild marine environment, and sharks are absent and missing from the numbers they have been in for many, many years, and seals have been hunted to near extinction."
Several solutions have been proposed to keep sharks off shore, including a $ 100,000 underwater fence (£ 82,116).
Carlstrom said the technology protections are "intriguing," adding that "it would be amazing to be able to do something that is reliable, economical and completely thought out at some point in the future."
However, he admitted that additional detection fences or buoys may not work in Cape Cod's choppy waters.
