Sun Coral Tubastraea faulkneri is a large polyp stony coral from the family Dendrophyliidae. The species occurs all over the tropical Indo-Pacific Ocean in a wide depth range of 3-225 meters, often in greater densities on vertical walls and caves. \nThese corals are slow growers and they do not contribute to coral reef development. Unlike many tropical corals, they are azooxanthellate or non-photosynthetic, meaning that they do not live in symbiosis with zooxanthellae in their tissues, allowing them to grow in complete darkness as long as they can capture enough food, usually plankton. \nThey extend their translucent tentacles like these specimen during the late evening and the night, while during the day the tentacles are completely withdrawn. \nTriton Bay, West Papua Province, Indonesia, 3°54'2.454 S 134°6'23.7 E at 14m depth

Orange Cup Coral Tubastraea coccinea occurs in tropical and subtropical Western Atlantic and Indo-Pacific in a depth range from 1-37m. This large-polyp stony coral is not a reef building species. The coral extends beautiful translucent tentacles at night. 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.\nThis large colony has fully open polyps during the day, \nbecause they are on the side facing away from the sun under a ledge. \nTriton Bay, Kaimana Regency, West Papua Province, Indonesia\n3°54'50.604 S 134°6'0.828 E at 6m depth
