''Acanthastrea regularis'' is a species of coral found in Indo-Pacific waters from Australia to the western Pacific Ocean. It is usually uncommon throughout its range, but can be more common locally. It has a narrow depth range, and so is susceptible to coral bleaching and disease. It is also threatened by the global decline in coral reef habitats. ==Description== Colonies of ''Acanthastrea regularis'' are massive. The corallites are subplacoid and are irregularly placed. The septa are neatly arranged, with the teeth on adjacent septa often aligned creating concentric rings. The skeleton is not covered with fleshy tissue and the colony colour is brownish or yellowish-brown, often with the floor of the corallites and the corallite walls being contrasting colours.〔(【引用サイトリンク】title=''Acanthastrea regularis'' )〕
