Description
Color: Uniform blue, cream or pale brown

Colonies are arborescent to caespitose in growth form. Corallites are widely spaced. The coenosteum is fine, thus giving branches a smooth appearance. Secondary branches are bent against the side of the main branches. The radial corallites mostly vary in shape, size and orientation among the same branch. The primary septa are obvious. The surface of the coenosteum is spiny. The primary branches are more or less equal in width from apex to bottom. The branches of the colonies are close together.

Hermaphroditic, broadcast spawning.

Similar species: Growth forms and habitat preferences are similar to those of Acropora horrida. Irregularly branching, tree-like, with a rambling growth form (Source: WoRMS)
