Red Algae
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and centrioles, chloroplasts that l ...

Compsopogon
''Compsopogon caeruleus'' is a species of red algae that lives in fresh water. It is the only species in the genus ''Compsopogon'' and the only representative of the family Compsopogonaceae. It is found in North America, South America, Europe, Africa, Asia, Australasia and Oceania. ''Compsopogon'' can tolerate a wide range of conditions in freshwater streams and occasionally in brackish lagoons and estuaries. It propagates by asexual spores. ''Compsopogon'' presents a thallus of simple cylindrical cells inside large covered cortical cells. In more mature and large thallus interior cells can be disintegrated, leaving only the outer cortex. The species exhibits a wide phenotypic In genetics, the phenotype () is the set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological proper ... plasticity in studies such as field observations, ...
