Characters: Colonies are usually elongate and generally have rounded ends. Mouths occur within the axial furrow which runs most of the length of the colony. Secondary mouths outside the furrow are numerous. Few if any primary septo-costae extend from the axial furrow to the perimeter. Some colonies develop forked axial furrows and become Y, T or X shaped. Tentacles are extended only at night.
Colour: Pale or dark brown or greenish-brown.
Similar species: Herpolitha weberi.
