But why do killer whales assault great white sharks? Allow’s dive into your science powering this interesting predator struggle.
The Rise of Orca vs. Shark Encounters
For decades, good white sharks were regarded the undisputed kings of your ocean. Even so, recently, maritime biologists have documented multiple incidents in which pods of orcas have hunted and killed good white sharks, especially off the coast of South Africa, California, and Australia.
Among the most famous circumstances transpired in 2017 around South Africa, when scientists learned quite a few great white sharks washed ashore with their livers missing, a telltale signal of orca predation. Considering that then, very similar styles are actually noticed in other locations, primary researchers to research why these attacks are occurring additional commonly.
How come Killer Whales Focus on Good White Sharks?

How Are excellent White Sharks Responding?
Interestingly, great white sharks appear to be changing their actions in reaction to enhanced orca attacks. Some researchers suggest that terrific whites are avoiding common looking spots wherever orcas are already sighted.
