Coralline algae are red algae in the order Corallinales. They are characterized by a thallus that is hard because of calcareous deposits contained within the cell walls. The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or gray-green.
Jania rosea is a species of coralline algae. [2] [3] [4] References This page was last edited on 18 November 2024, at 19:08 (UTC). Text is available ...
The coralline algae has a rough and chalky texture, and the color can range from grey, brown, and pink. They are thin and will attach very strongly to the surface. The individuals of the species are small, when young the algae's diameter can be up to 8 mm, but when mature the diameter is around 25 mm. Younger specimens will be relatively thin ...
Jania is an articulated coralline algae characterized by having erect thalli with dichotomously-arranged branches composed of alternating segments of red or pink, calcified, cylindrical sections (intergeniculum) and white uncalcified sections (geniculum); that is attached to the substrate by small, stolon-like holdfasts.
[27] [28] Coralline algae are particularly sensitive to ocean acidification because they precipitate high magnesium-calcite carbonate skeletons, the most soluble form of CaCO 3. [ 29 ] [ 30 ] [ 23 ] Calcification rates in coralline algae are thought to be directly related to their photosynthetic rates, but it is not clear how a high-CO 2 ...
There are many variations of crustose, including Crustose Coralline Algae (CCA), found in three different habitats; flat, crest and slope reef. [8] CCA are highly dependent on sunlight to grow in abundance, and their growth increases productivity. CCA acts as the main food source for certain fish including parrotfish and Scarus trispinosus.
