Ocean Odyssey on Instagram: "Near the plunging walls of Tubbataha Reefs Natural Park in the Sulu Sea, divers documented a rare longfin dragonfish (Tactostoma macropus) in open water. The dragonfish was hunting for prey as seen by the flowing filament in its mouth known as a bioluminescent barbel. The barbel is used to lure prey from the deep’s darkness. #ocean #oceanlife #deepwater #underwater #explore #fyp"
