Isopora crateriformis

(Gardiner, 1898)


Studer, 1878

Characters: Colonies are solid encrusting plates sometimes over one metre diameter. Plates are covered by corallites of irregular sizes and shapes, sometimes with a tendency to form short branchlets. Axial, incipient axial and radial corallites all intergrade and all corallites are smooth and rounded.

Colour: Pale brown, commonly with pink or blue margins.

Similar Species: Isopora cuneata, which has larger, more uniform corallites. See also Acropora minuta. Can readily be mistaken for an Astreopora with small corallites underwater.

Habitat: Shallow reef environments, especially reef flats exposed to strong wave action.

Abundance: Common in Indonesia.

Taxonomic Note: May be difficult to separate from other encrusting Isopora species.
