Interestingly, while the lipid-rich livers are thought to be the primary target of these attacks, there was no photographic evidence of the orcas consuming it. In fact, no photos have ever been taken of this happening.

Whale sharks are gentle, filter-feeding giants, but orcas in Mexican waters were documented attacking the animals and devouring their livers.

A pod of killer whales has been spotted hunting the world's biggest fish, the whale shark, which is the first recorded case.

Orcas appear to select the youngest fish, work together to flip them upside down, then target the most vulnerable areas of their bellies.
