Koh Tao Marine Life

Underwater Geography

The coral reef ecosystem that lies along the island of Koh Tao, Thailand provides a home to bountiful marine life.

There are great opportunities for snorkeling, and many are accessible directly from the beach. The undersea rock formations vary from pinnacles stemming from the seabeds, some breaching the surface, to stacked boulder arrangements that provide swim-throughs and caverns for more experienced divers to explore.

Koh Tao Fish, Marine Life and Coral

Similar to those found in all tropical regions around the world, the marine fauna and flora around Koh Tao provide a natural aquarium for both snorkelers and divers. The different species of colourful angelfish, butterflyfish, bannerfish and stingrays are abundant on reefs. Hard corals such as table coral, staghorn coral, mosaic and mushroom corals are predominant within this region of the Gulf of Thailand. Koh Tao provides the perfect opportunity for divers to observe the relationships that make up the marine ecosystem.
