Geology
Apo Reef can be found around 33 kilometers west off of the mid-western coast of the Philippine island of Mindoro. Two separate coral reefs make up the atoll-reef system. The two reefs are separated by a 30 meter-deep channel between them. Several environments can be found within the reef's boundaries. Aside from coral reefs, seagrass meadows, beds of macroalgae and mangrove stands are present on and around the reef proper.
