Two “serial killer whales” have been caught splitting open great white sharks “with surgical precision” to eat their livers

SHARK are driven from their homeland by two serial killer whales who got a taste of their liver.

The brutal bunch have been terrorizing great white sharks off the coast of South Africa since 2017.

So far, seven dismembered remains have washed ashore with their livers gruesomely removed.

They also nibbled on some shark hearts.

It is believed that many more met a grisly end further out at sea.

The large numbers of great white sharks that usually congregate in the area seem to have got the tip and decided to head elsewhere to avoid the same fate.

Researchers say the large-scale avoidance strategy is similar to wild dogs in the presence of lions.

Of course, it’s not uncommon for orcas to kill sea creatures for dinner.

But rarely does it have such an impact on habitat.

Scientists were stunned to see sharks abandon areas where they traditionally roam.

Some tagged sharks walked for weeks and even months at a time.

“The more often the orcas visit these sites, the longer the great whites stay away,” said Alison Towner of the Dyer Island Conservation Trust.

“The research is particularly important because by determining how large marine predators respond to risk, we can understand the dynamics of coexistence with other predator communities; and these dynamics may also influence interactions between competitors or the predator-prey relationship within the guild determine.”

Great white sharks aren’t exactly weak either, with up to 300 razor-sharp teeth making them one of the ocean’s toughest predators.

So much so that the whale duo have their fair share of scars.

The dramatic shift is also having an impact on the broader ecosystem, as another shark species decides to move into open space.

The research is published in the African Journal of Marine Science.
