Among the most famed instances occurred in 2017 around South Africa, when researchers uncovered various terrific white sharks washed ashore with their livers lacking, a telltale indication of orca predation. Since then, comparable patterns happen to be observed in other regions, leading scientists to analyze why these assaults are occurring additional commonly.
