Scientists said that killer whales rip apart great white sharks off the coast of South Africa, eating their livers, hearts and testicles.
An autopsy of six sharks washed up by the waves on the shores of Gansby – about two hours from Cape Town – found they were “physically torn apart” by the whales in a “careful and polite” way.
Marine biologist Alison Towner said orcas tore shark skins just below the throat to create a cavity through which the liver – which weighs up to 180 pounds – slides.
The scientist discussed the results in an interview with Sharek YouTube channel, Newsweek Reports.
Towner said great white sharks do not usually die after attacks, which means they rarely become available for scientific studies.
“It was shock and disbelief when we heard that there was another great white shark on the beach with its livers ripped apart,” said the biologist.
“These injuries on the adult eggs were similar to those on Spingles in False Bay in that the animals were physically torn apart,” Ms. Towner explained.
“I think two animals had the heart removed and one male’s testicles removed. Because they’re so close to their body cavity.
“We think the killer whales were learning to grasp their pectoral fins. We don’t know for sure. It’s like a shredding motion. The liver … is greasy, very slippery, and it just naturally slips so they can come and share it.”
There have been reports of killer whales attacking sharks off the coast of South Africa since 2017.
In recent years, large numbers of whites have been found in False Bay, South Africa Steep decline.
Three years ago, five beasts of depth were found washed away by huge wounds measured from their sides.
Chilling, they all lost their livers.
There is a suspicion that two killer whales, Port and Starbord, which were spotted in the same part of the ocean, were chasing sharks so they could pluck out their fat livers.
Experts claim that predatory whales have acquired a taste for shark livers rich in oils and fats, providing a valuable source of energy for the huge marine mammals.
“To our knowledge, the absence of great white sharks from False Bay has not been recorded or reported,” said Marianne Newaudt, Cape Town’s environmental officer.
“Great white sharks are a major predator and we don’t know how their absence from False Bay will affect the ecosystem.
“We also don’t know the reasons for their disappearance. We still hope that the big whites will return to False Bay and we will announce our first visions when this happens.”
Orcas, also known as killer whales, are the largest member of the dolphin family.
Worldwide, it has been observed to prey on more than 140 animal species, including many types of bony fish, sharks and rays, and 50 different species of marine mammals, according to sea World.
Although they are carnivores, killer whales do not eat people or generally try to attack them.
The name “killer whale” comes from the fact that they have very complex team-oriented hunting methods, according to Facts about whale.
Ingrid Visser, an expert who has studied Orcas for nearly 20 years, says the monsters use powerful waves to propel sharks to the surface before attacking.
She said, “As soon as the shark is on the surface, the killer whale turns and raises its tail out of the water and descends on it like a piece of karate.”
