While in the broad and mysterious depths of the ocean, two apex predators reign supreme—killer whales (orcas) and great white sharks. When the two are known for their dominance from the maritime food items chain, recent proof has proven that orcas are not merely competing with excellent whites but actively looking them. But why do killer whales attack fantastic white sharks? Enable’s dive in the science guiding this intriguing predator struggle.
The Rise of Orca vs. Shark Encounters
For decades, good white sharks were regarded the undisputed kings on the ocean.

One of the more renowned instances transpired in 2017 close to South Africa, when scientists found out many excellent white sharks washed ashore with their livers missing, a telltale indicator of orca predation. Due to the fact then, identical designs happen to be observed in other regions, primary experts to research why these attacks are occurring a lot more often.
