''Astreopora'' is a genus of stony corals in the Acroporidae family. Members of the genus are commonly known as star corals and there are seventeen species currently recognized.


Description

Members of this genus mostly form dome-shaped or rounded heads but sometimes have leaflike extensions, be encrusting or form plates, vases and branches.Coral Hub
/ref> They are much larger than members of the genus ''
Montipora ''Montipora'' is a genus of Scleractinian corals in the phylum Cnidaria. Members of the genus ''Montipora'' may exhibit many different growth morphologies. With eighty five known species, ''Montipora'' is the second most species rich coral genus ...
''. They have a wide range of colours including yellow, brown, green, pink and blue but the most common are whitish-blue. The corallites are distinct and separate, sometimes raised on cones and sometimes depressed, up to four millimetres across and round in cross-section. The skeleton is porous with the coenosteum having a net-like appearance. The coral appears rough-textured because of tiny spines that cover the surface between the corallites. The Septum (coral), septa are poorly developed giving corals of this genus the appearance of being filled with holes.Classification of Scleractinian (Stony) Corals

Distribution

Members of this genus occur in the Red Sea, the Indian Ocean and the western Pacific. They are widespread but not particularly common and are a reef building species. They are found in a range of environments including shallow or muddy waters, as well as deeper areas of the reef where plating forms are most common. In shallow water they are inconspicuous and are never dominant. They may form heads of up to two metres in diameter and in deeper waters they may be much more common.


Ecology

The porous skeleton of these corals provide a home to a variety of polychaete worms that weaken the calcium carbonate structure by tunnelling into it. Several species of coral-inhabiting barnacles are associated with ''Astreopora''. In fact, ''Hiroa stubbingsi'' and two species of ''Cionophorus'' seem to occur nowhere else. In the case of ''H. stubbingsi'', which has a primitive wall and a relatively unspecialised Operculum (animal), operculum, this may be because it is not equipped to occupy other corals, but the ''Cionophorus'' species are smaller and it is an enigma why they are not found elsewhere.
