While it most likely zeroed-in on the nutrient-rich liver, multiple scavengers also got in on the meal.

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

Faced with a rash of shark deaths marked by brain swelling, Canadian and American scientists are trying to solve a marine mystery.

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