A great white shark was caught on video while it was attacking a seal off the coast of Cape Cod in Massachusetts Monday afternoon.

The recent sighting caused alarm and panic among beach goers after a warning was issued not venture too far from the shore.

The video, which was captured by onlooker CJ Martin, showed the shark “thrashing in the water” and was just yards away from where the terrified he was recording.

Daily Star UK reported that both the great white shark and the seal were “seen flailing” during their encounter.

Moments later, the shark's iconic dorsal sliced through the water as it turned red – a stern but grim signal that nature has once again taken its course and that one of the most feared creatures on earth has taken its latest victim.

The thrashing only calmed down when the great white shark appeared to be enjoying “feasting on the meal.”

Martin's video was posted by the Atlantic White Shark Conservancy on their Facebook page along with a caption that said, “September is a peak month of shark activity off Cape Cod.”

The nonprofit organization also issued a warning to visitors go out beyond waist deep water and shared a link on shark safety.

The uploaded video was viewed by 16,000 people, alongside 513 interactions and 70 shares.

Another great white shark was also caught on video while it was ravaging a whale carcass on September 1.

Geek.com posted that whale watchers caught sight of the shark while feasting on a minke whale carcass that was floating off the coast of Massachusetts near Duxbury Beach.

Duxbury Police Beach Operations had to close the beach after the carcass “attracted numerous sharks.”

They even managed to get a photo of the shark and posted it on their Twitter page.

Videos captured by the Plymouth harbormaster and onlookers depicted the shark “popping out of the water and enjoying its lunch.”

The source added that some whale watchers who were present at the time were “upset about the whale carcass,” while other were “excited” about seeing a great white shark.

Commercial fisherman Matt Riley also had a close encounter with the apex predator last month.

Riley, who posted the video on his Instagram account, said that it was “the most epic thing” that he had ever witnessed on the water.

“Great white sharks up to 20 feet in length feeding on a dead whale in Cape Cod Bay,” read Riley's caption.
