Porphyra umbilicalis, commonly called "laver", is a species of seaweed in the genus Porphyra. It is smooth in texture and forms delicate, sheetlike thalli, reaching 25 centimetres (10 in) long [1] and often clinging to rocks. [2] Porphyra is classified as red algae; it tends to be a brownish colour, but boils down to a dark green pulp when ...
Over 7,000 species are currently described for the red algae, [5] but the taxonomy is in constant flux with new species described each year. [41] [42] The vast majority of these are marine with about 200 that live only in fresh water. Some examples of species and genera of red algae are: Cyanidioschyzon merolae, a primitive red alga ...
Red seaweed refers to thousands of species of macroscopic, multicellular, marine algae in the taxon Rhodophyta The marine ecology is unusually varied for an area of this size, as a result of the meeting of two major oceanic water masses near Cape Point , and the park extends into two coastal marine bioregions .
Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of Rhodophyta (red), Phaeophyta (brown) and Chlorophyta (green) macroalgae.
Porphyra is a genus of coldwater seaweeds that grow in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species (from which comes laverbread), comprising approximately 70 species. [2] It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans.
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.
Asparagopsis taxiformis (red sea plume or limu kohu), formerly A. sanfordiana, [1] is a species of red algae, with cosmopolitan distribution in tropical to warm temperate waters. [2] Researchers have demonstrated that feeding ruminants a diet containing 0.2% A. taxiformis seaweed reduced their methane emissions by nearly 99 percent. [3]
Grateloupia turuturu is a large species of seaweed that has several shades of coloring such as red, maroon, and burgundy. [3] However, it may also be yellow when dying or deceased. It is soft and gelatinous in texture. The blades of the organism vary in size and shape; typically 1 to 8 blades will stem from a center, attached by a cylindrical ...
