The Increase of Orca vs. Shark Encounters
For many years, excellent white sharks ended up considered the undisputed kings in the ocean. However, in recent times, maritime biologists have documented various incidents exactly where pods of orcas have hunted and killed wonderful white sharks, significantly off the coast of South Africa, California, and Australia.
Just about the most well known conditions occurred in 2017 near South Africa, when researchers identified various terrific white sharks washed ashore with their livers lacking, a telltale indication of orca predation. Because then, comparable patterns have already been observed in other regions, leading scientists to analyze why these assaults are occurring additional commonly.
Why Do Killer Whales Focus on Wonderful White Sharks?
The Nutritional Worth of Shark Livers
Killer whales are extremely intelligent and strategic hunters.
