GENERAL CHARACTERSTICS OF MONTASTRAEA OR STONY CORAL
- Commonly called as stony coral or star coral.
- Contains ectodermal, calcareous or calcium carbonate skeleton, called as corallium.
- Colony is compact and massive produced by buds, growing more or less parallel with each other.
- Skeleton is very hard like stone.
- Surface of the body contains closely-placed cups or corallites containing polyps.
- Zooids are separated by a solid coenosarc.
- Coenenchyma is produced by calcification of coenosarc which also gives rise to corallites. Corallites lie in close contact with each other.
- montastraea is a poreless coral reproducing by gemmation, fissiparous division and budding.
The animal contains hardened calcification and closely fitted caps for polyps and all above characters and hence it is Montastraea.
