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. This large colony has fully open polyps during the day, because they are on the side facing away from the sun under a ledge.

The color of Gorgonian Seafan Annella mollis varies and ranges from cream-colored to pink and orange. The close-meshed skeleton of the species in the family Subergorgiidae consists of fused sclerites and gorgonin, so it is extraordinarily flexible and thus perfectly adapted to strong currents. This white specimen, unusual for that region, is bleached. A lot of small fishes, mainly Anthias and Damselfishes are there. Palau, Micronesia, 6°59'10.52 N 134°13'7.34 E at 32m depth
