The coralline algae lives in the mid-tide and higher level pools, occasionally exposed to air. [4] The coralline algae mostly grows on hard rock surfaces and was not found on any limestone or slate rock. [4] It can also be found growing on the shells of mollusks that live in the same area, however the algae was physically reduced on the shells. [4]
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 ...
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.
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. [9]
[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 ...
