Creature of the Month: Cup Coral, Tubastraea coccinea
The cup coral Tubastraea coccinea is the pretty, orange, tubular coral which you see growing in underhangs, drop-offs and reef slopes in strong currents. At night the coral skeleton - corallum - is hidden by lovely ring of bright yellow tentacles. During the day the tentacles are retracted into the coral tube.
The name comes from the Latin for tube (tubus) and the Greek for star (astron). The skeletal tubes measure 5-15 mm across and protrude by 10 mm or more from the coral surface. Tubastraea species occur from the surface to depths of nearly 1500 m. There are four or five species throughout shallow Indo-Pacific waters (Red Sea, Thailand, Indonesia, Hawaii, etc.). Orange Cup Coral is also found in cold water.
As Tubastraea grow in low light, they lack symbiotic algae (which require light to photosynthesise). This in turn means that they grow relatively slowly and do not contribute to reef building. They are also known as Sun Coral or T. aurea.
Class: Anthozoa > Subclass: Hexacorallia >Order: Scleractinia > Family: Dendrophylliidae
