Dramatic video shows a white shark devouring a seal off Chatham

In a scene that they described as spectacular, researchers this weekend were treated to an up-close look at a great white shark dining on its prey near Chatham.

The Atlantic White Shark Conservancy, the nonprofit working with the state’s Division of Marine Fisheries on a five-year population study of the sharks off Cape Cod, posted a video of the encounter to social media early Monday morning.

“Our team got incredible footage of a white shark eating a seal,” they wrote.


Officials from the Atlantic White Shark Conservancy were not immediately available for comment, because they were back out on the water Monday continuing their research.

The 1½-minute video, which the conservancy paired with dramatic music, features a series of still photographs captured from a spotter plane high above the group’s research vessel, as well as slow motion footage taken from the bow of the boat.

It shows the great white shark — officials didn’t say how big it was — whipping its head back and forth underwater, as it sinks its teeth into the seal.

At some points in the video the shark’s head breaches the ocean’s surface, as it continues to thrash and gnaw at its prey. The photos interspersed throughout the footage show plumes of blood stretching across the emerald green ocean.

The video ends with the words “Welcome to Shark City!”


Although the summer season is over for humans, Cape Cod is still a prime location for great whites this time of year.

In a previous interview with the Globe, state marine fisheries scientist Greg Skomal said the sharks typically arrive in bulk in mid-to-late July, and can hang around until December.
