Andaman sea, Satun, Thailand. A school of Banana fusilier (Pterocaesio pisang) swim over a field of soft corals (Dendronephthya sp.) at Koh Ya Kha, Mu Koh Tarutao National Park, Satun province, Thailand. The large abundance of soft corals around the reefs of Satun is due to the nutrient-rich waters of southern Andaman sea.
