Great White Sharks Steal Fish Directly From Lines
2 Oct
Summary
- Sharks are aggressively taking fish from fishing lines, a behavior called depredation.
- This rare behavior has been observed off the coast of Cape Cod, Massachusetts.
- An increase in grey seals is linked to more white sharks in the area.
A newly released National Geographic video reveals great white sharks exhibiting a surprising behavior: aggressively snatching fish from active fishing lines. This phenomenon, termed shark depredation, was captured by photographer Brian Skerry off the coast of Cape Cod, Massachusetts.
Skerry noted that this footage corroborates accounts from fishermen who have witnessed juvenile great whites increasingly taking fish mid-catch. He highlighted that some captains have reported seeing dozens of such incidents within a single season. This behavior suggests predators are associating fishing activities with readily available meals.
Marine researchers have observed a rise in great white shark sightings, particularly in the Cape Cod area, which is attributed to a growing population of grey seals, a favored prey. While this indicates a healthy ocean ecosystem, it also signals ongoing changes within marine environments.
