Colin, P.I., 1978. New World Publications, Inc., Paramount Miller Graphics, Inc., Jacksonville, Florida. T.F.H. Carpeting Halimeda (Halimeda Opuntia)is a calcified member of the popular Halimeda family, and is a green macroalgae. horizontally. Maximum likelihood phylogram inferred from partial SSU nrDNA, ITS1, 5.8S rDNA and ITS2 of 47 specimens of Halimeda species and two outgroup species (see Table 2). The irregular oval segments of Halimeda appear as several small green coins glued from end-to-end, forming a chain. The Halimeda plant is a green calcareous macroalgae found within tropical oceans worldwide, and is a beautiful decorative plant for a marine aquarium. The branches are numerous and are in different planes, rather than nearly in a single plane as some other species are. Halimeda is a genus of green macroalgae. Halimeda opuntia. For this reason, Halimeda may also be called the Money Plant. 30. Voss, G.L., 1976. Introduction. but is an encrusting variety that spreads both laterally and Description. 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. As for Halimeda monile and H. macroloba showed no … Publications, Inc. Ltd. Humann, P., 1993. For each biochemical analysis, a different homogenization buffer was used (see Supplementary material). halimeda opuntia An abundant, heavily calcified algae that is a major producer of carbonate sand throughout the Caribbean. Disclaimer: ITIS taxonomy is based on the latest scientific consensus available, and is provided as a general reference source for interested parties. Halimeda's resistance to grazing and their tendency not to overrun and damage sessile invertebrates make them a far better choice as a decorative and functional alga than Caulerpa. Similarly, Comeau et al. This algae is capable of living under low-moderate light, it will grow strongest in moderate to high lighting. A Large spreading plants subtidally. Green to chalky white . The section Opuntia within the green seaweed genus Halimeda includes sprawling and pendant thalli composed of strongly calcified segments.

Deloach). Short description Morphology Thalli form greenish to cream amorphous clumps, attached by rhizoids at various points where segments get in contact with the substrate. Caribbean reef invertebrates and plants. However, it is not a legal authority for statutory or regulatory purposes. Campbell et al. Each individual thallus (frond) consists of a single cell forming a tube with multiple cell nuclei. Sometimes forming rather large 'thickets' covering an area of 40-50cm.

This particular Description Halimeda Plant is a green calcareous macroalgae that is a prized decorative plant in marine aquariums. (Halimeda cuneata f. digitataand Halimeda opuntia), in situ rates of oxygen fluxes and calcification in light and in darkness, organic‐, and inorganic carbon content and carbon isotopic signatures (δ13C) were compared between CO2seep and control site. Detail of primary and secondary utricles (ds). This alga can cover larger areas with a dense mat so that individual plants are indistinguishable. Short nodal fusion in paired groups (ls). The genus Halimeda Lamouroux is characterized by a coenocytic thallus constructed of a system of interwoven bifurcated siphonous filaments that expand into utricles at the thallus surface. Halimeda (Caulerpaceae) is a calcified green alga that is widespread today and important as a structural component of many Cenozoic–recent reefs; the genus is estimated to be responsible for ,25–30% of the CaCO 3 in Neogene fossil reefs (Stanley and Hardie, 1998). It features tight segments of calcified discs that form rather large mounds with several holdfasts anchoring each colony to rocks, sand and hard bottom. With regard to the habitat of Halimeda in the Laccadives, the following interesting note on H. opuntia , Lamx. (Linnaeus) Lamouroux, 1812.
