UNESCO says:
The Tubbataha Reef Marine Park covers 33,200 ha, including the North and South Reefs. It is a unique example of an atoll reef with a very high density of marine species; the North Islet serveing as a nesting site for birds and marine turtles. The site is an excellent example of a pristine coral reef with a spectacular 100-m perpendicular wall, extensive lagoons and two coral islands.
