The Tubbataha Reefs Natural Park is a protected area of the Philippines located in the middle of Sulu Sea.
The national park and the rest of the Philippine archipelago is part of the Coral Triangle, recognized as a center of marine biodiversity containing 75% of the described coral species and 40% of the world's reef fish.[6] The area is under a grave threat due to overfishing and destructive fishing practices.[7] Research of scientists visiting the reefs since the 1980s revealed that the Tubbataha Reefs Natural Park contains no less than 600 fish species, 360 coral species, 11 shark species, 13 dolphin and whale species, and 100 bird species. The reefs also serve as a nesting ground for Hawksbill and Green sea turtles.
