Siderastrea
Siderastreidae is a Family (biology), family of reef building Scleractinia, stony corals. Members of the family include Symbiosis, symbiotic algae called Zooxanthellae in their tissues which help provide their energy requirements. Description Members of this family are Colony (biology), colonial, hermatypic (reef-building) corals. The corals vary in form and include massive, thickly encrusting, columnar, and irregular forms. The corallites are linked by flowing Septum (coral), septa that have granular margins and that are fused in the centre to give fan-shaped or star-shaped groupings. The corallites do not project from the surface of the coral and have ill-defined walls formed from thickened septa.Family Siderastreidae WetWebMedia.com. Retrieved 2011-12-18.

Siderastrea Siderea
''Siderastrea siderea'', commonly known as massive starlet coral or round starlet coral, is a stony coral in the family Siderastreidae. It is found in shallow parts of the western Atlantic Ocean as solid boulder-shaped or domed structures. Description ''Siderastrea siderea'' is a colonial coral that forms low domes or boulder-shaped structures with a smooth dimpled surface as much as wide on the seabed. It can be encrusting when young. The corallites, the calcareous cup-shaped depressions in which the polyps sit, are about wide with about 50 or 60 little ridges called septa. The general colour is reddish brown. This species can be confused with the closely related lesser starlet coral ('' Siderastrea radians'') but that is usually smaller and has deeper, more angular corallites, each with 30 to 40 septa. Distribution and habitat ''Siderastrea siderea'' is found in the Caribbean Sea and the northern Gulf of Mexico and round the coasts of southern Florida, the Bahamas and Be ...

Siderastrea Radians
''Siderastrea radians'', also known as the lesser starlet coral or the shallow-water starlet coral, is a stony coral in the family Siderastreidae. It is found in shallow parts of the western Atlantic Ocean as small, solid mounds or encrusting sheets. Description ''Siderastrea radians'' is either encrusting or grows in small, dimpled hummocks up to across but most colonies are much smaller than this. Occasionally it occurs as small calcareous pebbles that roll around in seagrass meadows or as loose flat discs in shallow rocky places. The corallites are not circular but are triangular or four-sided and deep, with 30 to 40 small ridges called septa. They have a dark interior that contrasts in colour with the pale surface of the coral which is greyish, greenish or light brown. The polyps are retracted back into these corallites during the day but emerge at night, extending their tentacles to feed. Each of these has a small knob of stinging cnidocytes at its tip.

Siderastreidae
Siderastreidae is a family of reef building stony corals. Members of the family include symbiotic algae called Zooxanthellae in their tissues which help provide their energy requirements. Description Members of this family are colonial, hermatypic (reef-building) corals. The corals vary in form and include massive, thickly encrusting, columnar, and irregular forms. The corallites are linked by flowing septa that have granular margins and that are fused in the centre to give fan-shaped or star-shaped groupings. The corallites do not project from the surface of the coral and have ill-defined walls formed from thickened septa.Family Siderastreidae WetWebMedia.com. Retrieved 2011-12-18.

Cnidarian Families
Cnidaria () is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments, predominantly the latter. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. Cnidarians mostly have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes. Both forms have a single orifice and body cavity that are used for digestion and respiration. Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors. Several free-swimming species of Cubozoa and Scyphozo ...
