Recent findings used wildlife forensics and citizen science data to provide the first confirmed evidence of killer whale predation on white sharks in Australia.

Based on DNA analysis from the bite wounds on the carcass of a large white shark washed ashore near Portland in Victoria in 2023, the Flinders University-led study identified that killer whales were responsible for consuming the mid-section containing the nutritionally rich liver.

The recent autopsy of a partially devoured great white shark confirms a brutal hunting trend— killer whales around the world are not afraid to attack the fearsome fish, especially when they get a taste for liver.

Great white sharks are washing up dead on beaches with enlarged brains in what is becoming a spiralling marine mystery.
