Polysiphonia is a genus of filamentous red algae with about 19 species on the coasts of the British Isles and about 200 species worldwide, including Crete in Greece, Antarctica and Greenland. [3] [4] Its members are known by a number of common names. Polysiphonia is a member of the order Ceramiales. The genus Polysiphonia derives its name from the polysiphonous nature of its thallus. The central siphon is surrounded by 4–24 pericentral siphons. Polysiphonia is commonly found as an epiphyte on plants and lithophyte on rocks in brackish estuaries in the intertidal and sublittoral regions. Polysiphonia, a common genus of marine red algae, is red in color because of the pigment phycobilin, which masks the green color of the chlorophyll responsible for photosynthesis.
