Scientists documented a never-before-seen killer whale hunting behavior off Cabo San Lucas that left a giant sunfish in thousands of pieces.
Scientists captured video of orcas ramming into sunfish with such force that the fish exploded. The behavior may be for fun as well as for feeding, they report.
Researchers for the first time have documented orcas cooperating to smash their prey. Both instances were captured on video.
