Coral reefs are the one of earths most complex ecosystems, containing over 800 species of corals and one million animal and plant species. Here we see a shallow coral reef with Gorgonian Sea fan corals supporting shoals of Bigeye Snapper (Lutjanus lutjanus). The large school of fish group together as a means of protection from predators. Coral reefs are also critical in the carbon cycle of planet earth. They absorb calcium ions and dissolved carbon dioxide from the water. The location are the Bida Islands, Phi Phi Archipelago, Andaman Sea, Krabi, Thailand.
