Orcas make more targeted attacks on Great White Sharks
Two years ago Swellnet reported on a top-of the-food-chain fight that went down at the Neptune Islands off South Australia. In front of a bunch of cage diving tourists "six orca whales herded a Great White Shark and began to attack it by launching out of the water and slamming down on it."
The result from that lopsided assault was an exodus of Great White Sharks from the Neptune Island area and the subsequent collapse of the cage diving industry.
Showing it wasn't a one-off event, similar attacks recently occurred in South Africa. And in a grisly twist the Orcas have been targetting the White's organs; several carcasses have been found without livers and two with their hearts also missing, while the stomach and testes had been removed in the most recently found carcass.
The autopsy on that shark was done by the Dyer Island Conservation Trust team who updated their findings in a Facebook post:
The deceased male shark measured 4.1m in total length. He was missing his liver, his testes and stomach. The carcass may be a few days old but it seems relatively fresh and bled out massively. All necessary samples have been taken for the various scientific projects.
"This is the 4th documented deceased white shark since May that we can connect to Orca predation" said Towner [Alison Towner, White Shark biologist]
The pair of Orcas believed to be responsible were sighted offshore of Danger Point then again in Franskraal today. Marine Dynamics cage diving boat tracked the pair. Subsequently all cage diving boats failed to see white sharks today and it is believed the sharks may have fled the area once again.
In a field where knowledge is scant and attacks unpredictable, there appears a recurring pattern with Orcas and White Sharks.
Also makes you wonder who the actual apex predator is - underneath humans, that is.
