The great white shark, Carcharodon carcharias, is considered the most voracious apex predator in temperate marine ecosystems worldwide, playing a key role in controlling ecosystem dynamics.
As a result, it is difficult to imagine a great white as prey. And yet, earlier this year the carcasses of five great whites washed ashore along South Africa’s Western Cape province. Ranging in size from 2.7 meters (9ft) to 4.9 meters (16ft), the two females and three males all had one thing in common: holes puncturing the muscle wall between the pectoral fins. Strangest of all, their livers were missing.
The bite marks inflicted, together with confirmed sightings indicate that orcas, Orcinus orca, were responsible for this precisely-targeted predation.
The diet of orcas is often geographic or population specific. Those populations predating in South African waters have been documented targeting smaller shark species for their livers. Cow sharks, blues and makos caught on longlines have had their livers removed by orcas, alongside the brains of the billfish also caught. Cow shark carcasses without livers have also washed ashore near Cape Town, and again, this followed nearby orca sightings.
With no doubt that orcas are using highly specialized hunting strategies to target the liver; the real question is: why?
