Cyphastrea


Under construction

Cyphastrea (Faviidae)

Welcome to the Cyphastrea genus landing page. In this section, you will find general information about this genus and tips on how to identify it. If you are looking to confirm an observation made with the Coral Finder, use the image browser below to identify a growth form similar to what you saw underwater. Then choose one of the following links for further information: massive, or branching.


Vital Statistics

  • 8 species
  • Coral Finder p. 1c, 4c, 10
  • COTW – Vol 3 p.240-249

Distribution

Widespread in the Indo-Pacific.

ID Tips

Generally Cyphastrea forms low mounds or thick encrusting colonies, however one species, Cyphastrea decadia grows in a branching form with an arrangement of radial and axial corallites reminiscent of Acropora.  Cyphastrea may be found in a wide array of reef zones from the sub-tropics to the tropics.

The first thing to note regarding Cyphastrea corallites is their size: small.  Although photos of this genus may look similar to those of other genera, when scale is examined, it is clear that Cyphastrea corallites are considerably smaller, forming low cones of 2-3mm in diameter.

Costae run down the outer edge of the corallite walls feeding into the colony surface which is covered in beaded spinules.  Close examination is needed to see these structures in the field; a cursory glance is not sufficient!

Similar Genera

The Coral Finder lists Cyphastrea in one key group with Astreopora being a possible candidate for confusion.  Note however the comment one page 1 of the Coral Finder discussing the similarity of Cyphastrea decadia to branching Acropora.

Similar genera to massive Cyphastrea (Coral Finder p10)

Cyphastrea can be confused with Astreopora species, but may be easily separated by corallite size and appearance of the spinules.  Cyphastrea corallites are small (2-3mm in diameter) and the spinules forming on the colony surface are beaded and regular.  Astreopora generally has larger corallites (up to 4mm) and the spinules are ragged in appearance.

Massive Cyphastrea

Similar genus: Astreopora

Similar genera to branching Cyphastrea (Coral Finder p1c)

Cyphastrea decadia, a branching coral, can look superficially like Acropora species, but may be separated by the beaded spinnules covering the surface of the colony between corallites on CyphastreaAcropora does not possess similar structures.
