Great White Shark Filmed Snatching Fish Off Cape Cod Coast

A recent video captured off the coast of Cape Cod showcases a rare instance of "shark depredation," where a great white shark snatched a fish directly from a fishing line. The footage, filmed by National Geographic explorer Brian Skerry, is the first underwater recording of this behavior, which has become increasingly common in the area over the past three years.

Skerry, a Massachusetts native with extensive underwater experience, collaborated with local charter boat captains to identify locations with high shark depredation. After several days of filming, he documented a juvenile female great white shark rapidly taking a fish from a line on June 29.

Shark depredation, the act of sharks taking prey from fishing lines or nets, is not a new phenomenon. Historical accounts, including those by Ernest Hemingway in the 1930s, suggest it has occurred for over a century. However, fishermen in the Cape Cod region are now experiencing a significant increase in shark activity.

This surge in shark presence is linked to the recovery of great white shark populations in the North Atlantic, which were once close to extinction. The area around Cape Cod, with an estimated 30,000 to 50,000 grey seals, has become a prime feeding ground. The Marine Mammal Protection Act of 1972 has led to a boom in seal numbers, which in turn supports the growing shark population.

Sharks are typically present in these waters between May and October, coinciding with warmer temperatures. Research indicates that approximately 800 great white sharks frequented the waters off Cape Cod between 2015 and 2018, representing one of the densest seasonal populations globally. While this is beneficial for the marine ecosystem, it increases the likelihood of interactions between sharks and humans.

Hap Farrell, a local charter boat captain, reported numerous incidents of sharks taking fish, often coming within feet of his boat. He estimates at least 50 such events occurred in the past summer alone. Fishermen commonly report that the sharks involved are juveniles, typically measuring less than 10 feet in length. Adult grey seals, which can exceed 10 feet and weigh over 800 pounds, are formidable prey for young sharks, making hooked fish an easier target.

While the risk of shark attacks remains very low, with the last fatal incident in 2018, the increase in depredation is causing concern among fishermen. Gregory Skomal, a senior marine fisheries scientist at Massachusetts Marine Fisheries, noted that fishermen are voicing complaints about the sharks and the restoration of their populations. Conservationists worry that increased human-shark conflict could jeopardize the protected status of great white sharks, which play a vital role as "ocean architects" by regulating prey populations and controlling disease spread.
