Coral reef with Acropora coral (Scleractinia) at sandy bottom of tropical sea, underwater lanscape
An interesting reef: At five metres, large patches of branching Acropora and a three metre Turbinaria peltata colony were encountered. Hard coral cover averaged 60%, soft corals 22%, turf algae and sponges less than 1%, crustose coralline algae 18%. Table Acropora colonies exceed three metres in size.\nThe coral lesion repair was moderate, and both overgrowth of damaged portions of coral colonies and reorientation in growth plane of toppled corals were high.\n\nA large Table Acropora Coral dominates the scenery with some Isopora Corals around. \n\nMany fish species are in the background. \n\nBui Island, Indonesia\n5°5'13.77 S 131°55'36.654 E at 8m depth

colorful coral reef at surin island thailand
Orange Cup Coral Tubastraea coccinea dominate the scenery at this colorful rock overhang. \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. \n\nTriton Bay, Westpapua, Indonesia \n3°57'58.68 S 134°9'6.27 E at 9m depth

The surf zone is a special habitat. Due to the intensive movement of the water, many nutrients reach the sedentary organisms. Surf zones are also geologically interesting: when diving at depths of 10, 20 or more meters, you can easily recognize the surf zones of bygone eras. \nIt is not too bright under the rocky outcrop. Black corals also feel at home there in shallow water. Black Sun Coral Tubastraea micrantha, Sun Coral Tubastraea faulkneri, Hydroids and sponges are there too.  \nTriton Bay, Kaimana Regency, West Papua Province, Indonesia \n3°55'1.098 S 134°6'4.638 E at 2m depth
