This isn’t a random grudge match. Orcas are picky eaters, and a great white shark is mostly muscle and cartilage—not exactly a juicy steak. So why do it? It often comes down to one thing: liver.
Shark livers are packed with nutrient-rich oil called squalene. For a hungry orca, that liver is like a pure energy smoothie. They’ll kill the shark, take a single bite out of its side to extract the liver, and leave the rest to sink.

It’s weirdly respectful and horrifying at the same time. “Sorry buddy, just need your lunch. The rest of you can go.”
When the Shark Becomes the Prey
There’s a famous case off the coast of South Africa, near Gansbaai. For years, great whites were the main attraction for cage divers. Then, in 2017, a pair of orcas showed up and changed the whole ecosystem.
These orcas, nicknamed “Port” and “Starboard,” started killing great whites with surgical skill. The sharks didn’t just die; they fled. For months, no one saw a single great white in that area. The sharks literally packed their bags and left town.
Think about that: the ocean’s most feared predator got scared away by a couple of bullies with a taste for organ meat. It’s like a pack of wolves chasing a grizzly bear out of the forest.
