$Dendronephthya Soft Coral and Orange Cup Coral Tubastraea coccinea dominate the scenery at this colorful rock overhang. But there are Feather Star Fishes, Sponges and Colonial Ascidians too and a lot of Anthias and Damselfishes inbetween. \nIn the background there are Wrasses, Breams, Parrotfishes, Surgeonfishes and Butterflyfishes, a high biodiversity.\nTubastraea coccinea, a large-polyp stony coral, is not a reef building species. The coral extends beautiful translucent tentacles at night and in daytime on sunprotected areas of the reef like on this rock overhang. Tubastraea coccinea does not contain zooxanthellae in its tissues as many tropical corals do, allowing it to grow in complete darkness as long as it can capture enough food. \nTriton Bay, Westpapua, Indonesia 3°57'58.68 S 134°9'6.27 E at 9m depth$

An underwater scene featuring a stone (Ancient Coral Formation) in clear blue water. The stone showcases yellow algae on its surface. The water's transparency allows for a clear view of the stone and the intricate details of the algae growth. The photograph provides a straightforward depiction of the stone's presence within the aquatic environment, highlighting the natural occurrence of algae in underwater habitats. The combination of the stone, yellow algae, and clear blue water creates a visually interesting tableau, showcasing the simplicity and beauty found beneath the water's surface.
