Video: Scientists watch orcas ram a sunfish so hard it explodes

Marine biologists off Baja California recorded orcas ramming giant sunfish with such force that the fish exploded. A paper in Frontiers in Ethology documents three separate incidents in the Gulf of California. Researchers are investigating whether this behavior serves a specific purpose or is simply for entertainment. This activity adds to the orcas' recent repertoire of chaos, which includes terrorizing great white sharks and capsizing boats off the Iberian Peninsula, establishing them as charismatic ocean agents.
