Acropora irregularis   (Brook,  1892) (Hard Coral)
Organism information awaits expert curation
Taxonomy
Kingdom:Animalia
Phylum:Cnidaria
Class: Anthozoa
Order:Scleractinia
Family:Acroporidae

Description
Color: Usually grey

Colonies are primarily composed of highly fused horizontal branches. These may form tables over 3 m across or plates with a side attachment. Central parts of colonies may be almost solid. Most colonies, especially peripheral parts, are open branched. These may be few, if any, upturned branches. Corallites are irregular in length and tubular to rasp-like. Main branches sweep upwards, often reversing direction sharply. Lateral fusion of smaller side branches causes branch ends to become spade like, and further fusion may even lead to the development of semi-circular funnel shaped structures.

Hermaphroditic, sexual, broadcast spawning.

Similar species: Acropora robusta
