Great White Shark Circles Boat Off Cape Cod

PROVINCETOWN, MA — Boaters recently captured incredible footage of a great white shark slowly circling their boat off the coast of Provincetown. The footage was captured Sunday morning near Race Point Beach, which was closed Saturday after a separate great white sighting.

Also on Sunday, a photographer captured photos of a great white eating a seal off Race Point Beach.

There has been a surge in great white shark sightings near Cape Cod in recent years. Researchers last week discovered the reason why — there's a nearby nursery off Montauk, New York where adolescent great whites stay until they reach adulthood at the age of 20. Adult sharks then swim to Cape Cod to feed on seals, their primary food source.

It's been another busy summer of great white shark sightings on the Cape. On Sunday, Aug. 13, Lighthouse Beach in Chatham was closed after a great white shark was seen eating a seal nearby. On Friday, Aug. 5, Truro beaches were closed as six great whites fed on a dead minke whale nearby. In July, boaters credited an app for alerting them to a great white swimming alongside their boat — and a 6-year-old boy actually hooked a great whitein Cape Cod Bay (The shark was cut free.).

Shark attacks on humans are extremely rare — the odds are about one in 12 million. Most shark attack victims survive; bites on humans by sharks are normally exploratory.

Truro is the site of the last great white attack on a human in Cape Cod. On July 30, 2012, a great white bit a man on the leg. He survived.

The last close encounter in the region was September 2014, when a great white chomped a kayak with two women aboard off the coast of Plymouth. They were not hurt. The sharks might have mistook the kayak for a seal, which they prey on.

In 1916, a shark killed four people and seriously injured a fifth off the New Jersey coast — providing the inspiration for “Jaws,” which was filmed on Martha's Vineyard.
