Massive: Colonies are solid, boulder or helmets shaped and are typically hermatypical, 60% A&N Islands reefs covered by massive corals. Eg: Porites lutea Encrusting: Coral colonies which are form a thin layer or crust over underlying substratum. Eg: Montipora sp. Solitary: Corals composed of single individual and some coral can move little distance. Eg: Fungia sp. Foliose: Coral colonies attached at one or more points, leaf-life or plate like in appearance. Eg: Echinopora sp.
TYPES OF CORALLITES Ceroid: Adjacent corallites share the same wall. Eg: Favites Meandroid: In massive colonies that have corallite mouths aligned in valleys, these valleys separate by reticulated walls and there are no individual polyps. Eg: Symphyllia Placoid: Each corallite has its own separate wall. Eg: Favia Hydnophoroid: Septa fusing to form monticules or mould like structures. Eg: Hydnophora Phaceloid: Coral that have corallite of uniform height adjoined towards their base. Eg: Dendrophyllia
