Nemalion Helminthoides
''Nemalion helminthoides'' is a small marine alga in the division Rhodophyta. Description This is a fairly large erect alga which grows to no more than 0.4 m long. The frond is erect with a solid axis. It is very mucilaginous and with few branches which are elongate growing from a discoid base. The central strand is composed of filaments intricately entangled.Dixon, P.S. and Irvine, L.M.1977. ''Seaweeds of the British Isles Volume 1 Rhodophyta Part 1 Introduction, Nemaliales, Gigartinales.'' British Museum (Natural History) Habitat Midlittoral, epilithic and on ''Balanus''Hardy, F.G and Guiry, M.D. 2003. ''A Check-list and Atlas of the Seaweeds of Britain and Ireland''. The British Phycological Society. ''Patella''. Reproduction The life-history is not fully confirmed. However carpospore A carpospore is a diploid spore produced by red algae. After fertilization, the alga's carpogonium subdivides into carpospores, and generally the largest type of spore (larger than bispores, ...

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 ...
