The primary branches might possess dense clusters of smaller branchlets, creating a bush-like appearance in the colonies. Developing axial corallites can be plentiful. The radial corallites are sparsely distributed and differ in length. The coloration is typically a consistent blue, cream, or pale brown. These colonies usually have open branching structures and become denser, resembling bushes, especially on the upper reef slopes and in shallow lagoons. The coenosteum, the coral’s skeletal structure, is finely textured, giving the branches a smooth appearance that is visible underwater.
