Chinese Lettuce Coral

Mycedium elephantotus

Colonies are laminar or encrusting. Corallites are up to 15 millimetres diameter and nose-shaped, facing outward towards the colony perimeter. Septa and columellae are well developed and costae form outwardly radiating ribs on the colony surface which may become highly elaborated on corallite walls. The coenosteum is never pitted at the commencement of new septo-costae. Tentacles are usually extended only at night.
