Occurred on December 8, 2018 / Playas del Coco, Guanacaste, Costa Rica
Info from Licensor: "The video was recorded in the Gulf of Papagayo, Costa Rica. That day we traveled with the company Deep Blue Diving. It was the final part of the immersion in a place called Surprise. I started recording because it caught my attention that these two eels were fighting to the death."
