Coral reefs are underwater ecosystems relying on corals to ensure their subsistence. All species that inhabit these ecosystems depend directly or indirectly on corals. Often called “rainforests of the sea”, coral reefs form some of the most diverse ecosystems on Earth. They occupy less than 0.1% of the world’s ocean surface, yet they provide a home for 25% of all marine species. Coral reefs are commonly found at shallow depth in tropical waters, but some corals can even flourish in deep and cold water, as off the coast of Scotland for example.


Southeast Asia includes 32.3% of global coral reefs. The Andaman Sea is therefore very rich in corals and hosts an impressive marine biodiversity. Each dive sites proposed by SSSPhuket (such as Koh Racha Yai, Koh Racha Noi, Koh Dok Mai, Koh Phi Phi or the Anemone Reef) contain various corals reefs, all with their own characteristics and special “guests”.

Even if a coral head looks like a single organism, it’s in fact a group of many individual genetically identical living in tight colonies called «Superorganisms ». Each individual taken one by one are animals called polyps consisting in a central mouth surrounded by tentacles. Generation after generation, the colony creates a large skeleton, whose shape depends on the coral specie.
