The most popular situations transpired in 2017 near South Africa, when researchers identified quite a few fantastic white sharks washed ashore with their livers missing, a telltale sign of orca predation. Considering that then, identical styles are actually noticed in other locations, main experts to analyze why these assaults are occurring far more commonly.
Why Do Killer Whales Target Excellent White Sharks?
