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tentacles like these specimen during the late evening and the night, while during the day the tentacles are completely withdrawn.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

In large aggregations, Yellow Sea Cucumbers Colochirus robustus are often misidentified as corals. Colochirus robustus occurs in the tropical Central Indo-Pacific in a depth range from 1-25m, max. length 7cm. When feeding, the species extends the branchy feeding arms into the current. There are multiple reproduction options; instead of spawning, when getting large, the species can split into two: In a few days, the head end is ready to leave, whilst the rear end takes about a week to grow an own head! \nThese specimen aggregate on an old whip coral overgrown by sponges, hydroids and ascidians. \nTriton Bay, Indonesia \n3°55'0.858 S 134°6'6.102 E at 12m 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
