A marine biologist leading a scientific expedition to a remote island in Costa Rica was rushed to the hospital after being attacked by a giant shark. Dr. Mauricio Hoyos, 48, was bitten on the head while studying marine life in the Cocos Islands, a remote archipelago located approximately 340 miles off the coast of Costa Rica, known to harbor up to 14 different species of sharks. \u201cHe was tagging species for monitoring, and when he tagged one of the island\u2019s shark species, the shark turned,\u201d a physician with the Costa Rican Fire Department explained. \u201cIt was about 4 meters long (13 feet) with an enormous bite force\u2014it turned and bit him on the head.\u201d Hoyos, from Mexico, was transported back to the mainland, a gruelling 36-hour journey. He suffered severe injuries to the face, arm, and torso. \u201cIncidents like this are extremely rare,\u201d Alex Antoniou, executive director of research group Fins Attached, said on social media. \u201cDr. Hoyos is an extraordinary scientist who has dedicated his career to shark conservation, and we are deeply grateful for the support of the Cocos Island community in this very difficult time.\u201d<\/p>\n
