Several Great White Sharks Spotted In Cape Cod Waters

PROVINCETOWN, MA — More than a half dozen great white sharks were spotted off the Coast of Cape Cod Monday, aerial images from shark biologist John Chisholm show.

Chisholm in a Tweet said the sharks were seen along the coast from Plymouth to Provincetown. Some sharks measured up to 16 feet in length, according to Chisholm.

"Although it's hard to judge size without anything for scale in the photos, you’ll notice the > 16′ shark has a lot more girth,” Chisholm said on the MA Sharks Twitter account.

Chisholm has documented great white shark sightings in the Atlantic Ocean since the late 197os, according to his profile on the Anderson Cabot Center for Ocean Life website. He's collected data on more than 500 great white shark sightings, from Canada to Florida.
