While trolling for sailfish and dorado near Los Suenos, Costa Rica on February 8, Captain Mark J. Garry and crew witnessed something big-game anglers live for: an estimated 500-pound, free-swimming blue marlin in full-on attack mode. The marlin was after a big dorado that couldn’t seem to escape the crippling blows of the predator’s bill. It’s escape tactic was to take to the air. Fortunately, Captain Garry had the wherewithal to film the encounter.

“It wasn’t a good day to be a mahi mahi,” Captain Garry said in the video.

The last time Garry saw both fish, they passed five feet from his boat, but he was unsure if the dorado had gotten away.
