The ruler of the seas may appear black and white, but it’s not as simple as it seems. For years, great white sharks have been considered apex predators, but shocking new footage shows them feeding on their own kind. This is an event unlike anything we’ve seen before.
A video captured by tourists and scientists on a boat off the coast of Mossel Bay, South Africa was vital for scientific observations published in a recent study in the African Marine Science Journal. The footage revealed an unprecedented behavior of killer whales, showcasing their extraordinary abilities, according to the paper’s corresponding author, Dr. Alison Towner.
Witnesses on the boat watched as a juvenile great white shark, measuring 2.5 meters (8.2 feet), was attacked by a killer whale known as Starboard. The whale swiftly caught the shark by its left fin, thrusted it several times, and disemboweled it, likely targeting the shark’s liver for its rich nutrients. The entire attack lasted only two minutes, and the killer whale then revealed the shark’s entrails to the onlooking boats.
Subsequent research uncovered a second great white shark carcass nearby, measuring 3.6 meters (11.6 feet) in length.
In a previous study conducted in 2022, researchers found that killer whales can hunt great white sharks in pairs. By combining intelligence and strength, these whales can effectively surround and attack their prey. However, this recent attack marks the first time a killer whale has been observed hunting a great white shark alone.
This discovery not only enhances our understanding of killer whale behavior and marine ecosystems but also raises concerns among ecosystem scientists. There’s worry that if killer whales continue to prey on great whites, it could disrupt the food chain, allowing other predators to rise and challenge the great white sharks as the apex predators.
“Upon arriving at Seal Island in Mossel Bay, the smell of shark liver oil and an oil slick indicated a recent kill,” said a passenger on the boat named Esther Jacobs from the marine conservation initiative Keep Fin Alive.
“Seeing the fin of a great white shark break the water’s surface initially sparked excitement, but as the killer whale rapidly approached, it turned into a grim reality. The moment of predation was both devastating and incredibly powerful.”
