Goniastrea aspera

Verrill, 1905

Colonies are massive to encrusting. Corallites are angular in shape and have thick walls. Long and short septa generally alternate. Paliform lobes are well developed in colonies from turbid water but may be absent in colonies from exposed habitats.

Colour: Usually pale brown. Corallite centres are often cream.

Habitat: Usually intertidal habitats where different colonies may adjoin to form flat expanses frequently over 5 metres across. Also occurs in protected turbid environments.

Abundance: Sometimes common and may be a dominant species.
