Isophyllia
''Isophyllia'' is a genus of Scleractinia, stony coral in the subfamily Mussinae of the Family (biology), family Mussidae. Characteristics ''Isophyllia'' is a Colony (biology), colonial coral. Budding is always intracalicular, occurring inside the oral disc of the polyp, within the whorl of tentacles. The corallites are meandroid, that is, they are linked in a short series of up to five centres. The individual corallites are medium-sized, being in diameter and up to high. There are three or more cycles of Septum (coral), septa in each corallite, all equal in size. A narrow Costa (coral), costate coenosteum separates the corallites. Species The World Register of Marine Species lists the following species : *''Isophyllia rigida'' (Dana, 1848) *''Isophyllia sinuosa'' (Ellis & Solander, 1786) References Mussinae Scleractinia genera {{scleractinia-stub ...

Isophyllia Sinuosa
''Isophyllia sinuosa'', the sinuous cactus coral, is a species of Scleractinia, stony coral in the Family (biology), family Mussidae. It is found in shallow water in the tropical western Atlantic and the Caribbean Sea. Description and habitat ''Isophyllia sinuosa'' is a massive coral that forms hemispherical or dome-shaped mounds up to across. On the coral surface there are shallow, meandering valleys about wide separated by convoluted ridges topped with a central, pale-coloured line. The polyp (zoology), polyps are large and are situated in the valleys, often in groups of three. Although they are usually retracted into their corallites by day, they are unable to retract completely, giving the coral a fleshy feel when touched. The septa that radiate from the corallites are spiny. At night, when the polyps are fully extended, the coral has a fuzzy appearance. The ridges and valleys are usually made up of contrasting colours. These combinations include green/yellow, green/blue, pu ...
