Scientists confirmed this incident, which took place in June 2023, was the first ever record of a lone orca (Orcinus orca) hunting and consuming a great white shark (Carcharodon carcharias).
In a study publish March 1 in theAfrican Journal of Marine Science , scientists confirmed this case was the first ever platter of a solitary orca(Orcinus orca)hunting and consuming agreat white shark(Carcharodon carcharias)without the supporter of its podmates .
The incident take on lieu in June 2023 when researchers on a tourer sauceboat saw two orcas — bed as Port and Starboard because of their fall in dorsal fins — south of Seal Island , South Africa . The two orca alreadyhave a reputationfor attacking expectant white and feasting on their nutritious - plentiful livers — a new deportment that has ledgreat whites to abandon a popular search primer coat .
After approaching the grampus , the researcher comment an oily substance floating on the surface , birds plunk into the water and " the distinct flavour of shark liver , " according to the subject area . The researchers speculated that the pair of orcas may have already killed a shark before the boat go far .

" Once you ’ve sense it , you ’d recognize it again , " lead authorAlison Towner , a maritime biologist at Rhodes University , told Live Science in an email . She explicate that shark liver smells rich , fatty and not altogether unpleasant , but very hard to name .
well-nigh an time of day later , the sauceboat picture an 8 - foot - retentive ( 2.5 metre ) juvenile white shark at the surface with Starboard trail behind . " The orca giant push the shark forward by its pectoral fin while it thrashed on the surface , " Towner said .
By grabbing the shark ’s pectoral fin and excite it , Starboard tore the shark undecided in precisely the correct spot to polish off its liver .
A great white shark that was killed by orcas off the coast of South Africa.

A few minute afterward , a shark cage dive sauceboat that happened to be nearby visualize Starboard swim past " with a fucking piece of knockout - coloured liver in its oral fissure , " allot to the subject area . Port stayed around 330 feet ( 100 thou ) away throughout and was not involved in the depredation .
" The moment Starboard speedily prey on my favorite shark specie was both devastating and intensely powerful , " Esther Jacobs , the founder of shark conservation initiative Keep Fin Alive , who saw the attack , say in astatement .
Although the onlooker did n’t see the moment Starboard absent the shark ’s liver , as this happened underwater , Towner believes the shark would ’ve been killed like a shot .
The exact mechanism of how orcas shake a shark can tear it open is still unclear , but more clues arrived the next mean solar day when the carcass of a unlike great bloodless shark — this one measuring 11.5 groundwork ( 3.5 m ) — dampen up nearby . " The interesting reaching marks on its wing may suggest torsion induced by mosh , " Towner said .

— Orcas are hear terrify new behavior . Are they stick smart ?
Orcas target sharks ' fattyliversbecause of their high-pitched nutritional value . " Shark liver are pack with rich , oilylipids , making up to one third of their body mass in some species , " Towner said .
Sometimes known as thewolves of the ocean , orcas have secure social bonds and usually hound in groups . While they have been known to hound other species alone — includingseals , porpoise , and penguins — this is the first record of a unmarried killer kill a nifty white-hot . In premature accounts , blast have necessitate between two and six orca .
This determination may have of import conservation implications . " Altering the top predator balance has cascading impact , " Towner enunciate . " With most shark already facing various world - made pressure , orca predation adds further strain and could be a tipping detail in some region for some species . "
