Researchers studying orcas off the sea-coast of South Africa recently observed one of the whales consuming a great white shark alone , in just two minutes .
Since 2017 , two Orcinus orca in particular have beenwreaking mayhem on the great whitesoff South Africa ’s Mossel Bay . Dubbed Port and Starboard ( precious ! ) , the apex of the sun’s way predators have developed a preference for the massive sharks ’ nutritive - rich livers ( less cute).Haunting television of the whales actively feedingon a great white was captured in October 2022 , confirming that the cetaceans were responsible for the great blanched carcass line up half - eaten on the South African shores .
Orcas ’ preference for great white sharks is well - document ; the hulk can weigh up to 22,000 British pound ( 9,980 kilograms ) and are with child at gang up on the sharks , which only ( in comparison ) consider up to 5,000 punt . But never before have searchers found a individual orca dining on expectant white-hot ; antecedently , the animals have only been follow hunting and course in chemical group , or pods . The squad ’s analysis of the recent meal waspublishedin the African Journal of Marine Science .

“ Again , as previously in South Africa , the orcas are display a strong preference for extract and consume the lipid - rich liver of bloodless sharks — a specialised feeding behavior , ” say Alison Towner , a nautical life scientist at Rhodes University and lead generator of the newfangled research , in a Taylor & Francisrelease , “ This sighting revealed grounds of only hunt by at least one killer whale , gainsay conventional cooperative hunting behaviour know in the part . ”
The solitary hunting watch ( and diner ) was Starboard , a male orca with a give way dorsal fin . The researchers watched Starboard incapacitate and eat a puerile great ashen shark in two minutes . The unfortunate shark was 8.2 feet long ( 2.5 meters ) ; the squad also take in as Starboard channel the shark ’s liver in its mouth .
“ Over two decades of annual visits to South Africa , I ’ve observed the profound impact these cause of death whales have on the local white shark universe , ” said study co - generator Primo Micarelli , a researcher at the Shark Studies Centre and Siena University , in the same release . “ Seeing Starboard transport a white shark ’s liver past our vessel is unforgettable . ”

A brusk video of the skirmish was taken by members of the team aboard Shark Warrior , a catamaran about 330 feet ( 100 meters ) from the brush . The TV shows Starboard splashing off Mossel Bay , evidently predate on the shark . The investigator aboard Shark Warrior later snapped a photo of Starboard with the shark liver in his backtalk .
“ Despite my awe for these predators , I ’m increasingly concerned about the coastal marine ecology balance , ” Micarelli added . Tagging and spy data antecedently taken on the habitat suggestedgreat white sharks hold back visitingcertain areas along the coast due to the presence of orcas . In other words , the orca ’s hunger seemed to be impacting the food mountain range in the ecosystem .
Late last class , aliver - less great white washed up on the Australian coast , point that orcas beyond the group operating off South Africa had learned how to predate on the fearsome fish . Orcas alsofeed on blue whales(the magnanimous animal ever known),may kidnap other mintage of hulk , and wereresponsible for a spate of attackson human vessels last yr — even do to sink a yacht off the slide of Gibraltar .
Orcas are cute predators with an observable filthy streak . While they credibly wo n’t evolve to hunt on land anytime soon , their comportment could disrupt the hierarchy of the South African coastal ecosystem .
