Cyphastrea microphthalma

(Lamarck, 1816)


Milne Edwards and Haime, 1848

Characters: Colonies are massive, becoming thin encrusting plates where light levels are low. They commonly grow as mobile balls (coralliths). Corallites are tall and conical; compact in colonies exposed to strong light, widely spaced in encrusting colonies. They usually have 10 primary septa although this varies among corallites.

Colour: Brown, cream or green, sometimes other colours. Septa are commonly white.

Similar Species: Cyphastrea microphthalma is readily identified by its 10 primary septa which are visible underwater.

Habitat: Most reef environments.

Abundance: Common, but less so than C. serailia.

Taxonomic Note: The type species of Cyphastrea Milne Edwards and Haime, 1848 by subsequent designation, Matthai (1928). It is very polymorphic.
