Orcas are hunting sharks in the Gulf of California, targeting large species including bull sharks and blacktips, scientists reveal.  

Three orcas, or killer whales, are behind the attacks, and researchers say it is unclear what impact these hunts could have on the ecosystem, and whether sharks will eventually decide to leave the area.
