Detail of primary and secondary utricles (ds). 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. Photo by Kirby Adams. Aliquots (100–200 mg) of cold-ground H. opuntia were sonicated (ultrasound sonication, Cole-palmer ultrasonic processor model cp130) with homogenization buffer (1.5 mL) and centrifuged (10,000 g, 20 min, 4 °C). Calcareous algae deposit calcium carbonate in their tissues, and require a sufficient calcium level in the aquarium in order to thrive. The algal body (thallus) is composed of calcified green segments. 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). The Halimeda plant is a green calcareous macroalgae found within tropical oceans worldwide, and is a beautiful decorative plant for a marine aquarium. (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.

Halimeda opuntia. Within this section, identification of Atlantic mate-rial is straightforward, but Indo-Pacific material is often difficult to key out. Short nodal fusion in paired groups (ls). 28. Lamouroux, H. macroloba Decaisne, H. opuntia (L) Lamouroux, H. discoidea Decaisne and H. tuna (Ellis and Solander) Lamouroux. 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.

However, it is not a legal authority for statutory or regulatory purposes. Campbell et al. It features tight segments of calcified discs that form rather large mounds with several holdfasts anchoring each colony to rocks, sand and hard bottom. The branches are numerous and are in different planes, rather than nearly in a single plane as some other species are. [ 52 ] demonstrated that the calcification rate of Halimeda minima declined by 11.0% as p CO 2 doubled over ambient conditions. 30. Sometimes forming rather large 'thickets' covering an area of 40-50cm. Colin, P.I., 1978.

Halimeda opuntia. Description: Thick, profusely branched clumps of rounded three-lobed or ribbed leaf-like segments, between 10 and 25 cm in height. N. Deloach). Branches composed of moderately calcified flat segments with a distinct central rib, generally reniform to flabellate with the upper margin entire, sinuate to deeply lobed, 3 to 8 mm high, 4 to 10 mm wide, and 0.5 to 7 mm thick. The irregular oval segments of Halimeda appear as several small green coins glued from end-to-end, forming a chain. T.F.H. return to the bright green coloration within a few days. For the two most abundant Halimedaspp. The Halimeda plant is a green calcareous macroalgae found within tropical oceans worldwide, and is a beautiful decorative plant for a marine aquarium. but is an encrusting variety that spreads both laterally and (Linnaeus) Lamouroux, 1812.

This particular species does not possess a rhizome as other species of halimeda, but is an encrusting variety that spreads both laterally and horizontally. Each individual thallus (frond) consists of a single cell forming a tube with multiple cell nuclei. This algae is capable of living under low-moderate light, it will grow strongest in moderate to high lighting. noted that the calcification rates of H. opuntia and Halimeda simulans decreased by 15% and 50%, respectively, as a result of shifts in carbonate chemistry (pCO 2 = 2400 ppmv).

Caribbean, that do very well in tanks with high calcium levels 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. Introduction. You can continue searching for Halimeda opuntia on one of these Web sites: Fauna Europaea (animals) | IOPI (plants) | NCBI (genetic). Segmented usually with midribs. For this reason, Halimeda may also be called the Money Plant. The section Opuntia within the green seaweed genus Halimeda includes sprawling and pendant thalli composed of strongly calcified segments. Calcium carbonate is deposited in its tissues, making it inedible to most herbivores. These species are described in detail with original illustrations and an identification key. The cytoplasm is mobile and the nuclei, chloroplasts and other … 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). Reef Coral Identification - Florida Caribbean Bahamas, (ed. 0.5-2cm wide segments, with lengths of … such as reef aquaria. 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. Description: Blades are kidney-shaped calcified thick segments, 0.5-2 cm wide, with midrib down middle of segment.
