We ship several clusters approx 3"- They are commonly seen on many of our shores, usually growing on coral rubble or among living corals, as well as in sandy areas near reefs. Calcareous algae deposit calcium carbonate in their tissues, and require a sufficient calcium level in the aquarium in order to thrive.

For each biochemical analysis, a different homogenization buffer was used (see Supplementary material). Introduction. Halimeda is a genus of chlorophyte, which can be found in tropical and subtropical regions (El-Manawy and Shafik, 2008). The algal body (thallus) is composed of calcified green segments. Halimeda opuntia. For this reason, Halimeda may also be called the Money Plant. However one species, Halimeda tuna, was described as pleasant to eat with oil, vinegar, and salt. It features tight segments of calcified discs that form rather large mounds with several holdfasts anchoring each colony to rocks, sand and hard bottom. This alga can cover larger areas with a dense mat so that individual plants are indistinguishable.Habitat:They grow in shallow depressions, cracks and crevices, between hard corals and other somewhat protected areas of the reef, down to 55 m.Distribution:South Florida, Bahamas and Caribbean. Halimeda opuntia was used as a model organism to determine the effects of highly irradiated and shade conditions in the field and its responses to low light conditions in the laboratory, which are known to be some of the main factors driving its morphological plasticity. 0.5-2cm wide segments, with lengths of … The genus Halimeda has a wide geographic distribution in tropical to subtropical regions of the world. Colin, P.I., 1978. This particular species does not possess a rhizome as other species of halimeda, but is an encrusting variety that spreads both laterally and horizontally. Halimeda opuntia.
