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.
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 .
The Rhodophyta comprises one of the largest phyla of algae, containing over 7,000 recognized species within over 900 genera amidst ongoing taxonomic revisions. The majority of species (6,793) are Florideophyceae, and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats.
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.
Polysiphonia, known as red hair algae, [1] is a genus of filamentous red algae with about 19 species on the coasts of the British Isles [2] and about 200 species worldwide, [3] including Crete in Greece, Antarctica and Greenland. [4] [5] Its members are known by a number of common names. [note 1] [4] It is in the order Ceramiales and family ...
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 ...
Gelidium species have been collected, pressed and maintained in herbaria and personal collections from the 1850s onwards since seaweed collecting became a popular pastime for the middle classes as well as scientists in Europe and North America. [22] These numerous well-documented specimens can provide information beyond taxonomy. [23]
