Montipora
''Montipora'' is a genus of small polyp stony coral in the phylum Cnidaria. Depending on the species and location, ''Montipora'' may grow as plates or ridges, appearing to some as a bowl or flower. Undisturbed, the plates expand radially and may encrust over surrounding rocks, shells or debris. These corals are extremely common on reefs in the Red Sea, the western Indian Ocean and the southern Pacific Ocean, appearing as far north as Hong Kong. There are seventy five known species.〔(Classification of Scleractinian (Stony) Corals )〕 ==Description== Members in this genus are usually thin corals that form leafy, plate-like, encrusting or semi-massive colonies. The colours vary greatly. The calices are less than 2 mm in diameter and are usually well separated by the coenosteum. The skeleton is lacy, the walls are indistinct and the septa, when present are small and in 2 cycles. The columella is rarely developed and the corallites are inconspicuous and appear empty as the polyps are very small.〔
