Description
Color: Usually purple or cream.

Colonies are corymbose or prostrate, branches are terete. Radial corallites are of two sized, thick-walled. Axial corallites are larger, with very thick walls. Colonies are caespitose to caespito-corymbose in shape. The branches are terete or slightly tapering and curved. The radial corallites are of varied size, tubular or with dimidiate openings, sometimes interspersed with immersed corallites. Mostly corallites with dimidiate opening are dominant. The primary septa of the corallites are clearly visible. The coenosteum is closely packed with radial corallites and it is spiny. Usually incipient axial corallites are common at the base of the branches.

Hermaphroditic, broadcast spawning.

(Fisheries, human development (industry, settlement, tourism, and transportation), changes in native species dynamics (competitors, predators, pathogens and parasites), invasive species (competitors, predators, pathogens and parasites), dynamite fishing, chemical fishing, pollution from agriculture and industry, domestic pollution, sedimentation, and human recreation and tourism activities)

Ecology
Habitat:  Reef Associated
Trophic Level:  Consumer
Prey:  Shrimp, plankton, squid
