Spirulina (dietary Supplement)
Spirulina is a biomass of cyanobacteria (blue-green algae) that can be consumed by humans and animals. The three species are '' Arthrospira platensis'', ''A. fusiformis'', and ''A. maxima''. Cultivated worldwide, ''Arthrospira'' is used as a dietary supplement or whole food. It is also used as a feed supplement in the aquaculture, aquarium, and poultry industries.Vonshak, A. (ed.). ''Spirulina platensis (Arthrospira): Physiology, Cell-biology and Biotechnology.'' London: Taylor & Francis, 1997. Etymology and ecology The species ''A. maxima'' and ''A. platensis'' were once classified in the genus ''Spirulina''. The common name, spirulina, refers to the dried biomass of ''A. platensis'', which belongs to photosynthetic bacteria that cover the groups Cyanobacteria and Prochlorophyta. Scientifically, a distinction exists between spirulina and the genus ''Arthrospira''. Species of ''Arthrospira'' have been isolated from alkaline brackish and saline waters in tropical and subtro ...

Arthrospira
''Arthrospira'' is a genus of free-floating filamentous cyanobacteria characterized by cylindrical, multicellular trichomes in an open left-hand helix. A dietary supplement is made from ''A. platensis'' and ''A. maxima'', known as spirulina. The ''A. maxima'' and ''A. platensis'' species were once classified in the genus ''Spirulina''. Although the introduction of the two separate genera ''Arthrospira'' and ''Spirulina'' is now generally accepted, there has been much dispute in the past and the resulting taxonomical confusion is tremendous. Taxonomy The common name, spirulina, refers to the dried biomass of ''Arthrospira platensis'', which belongs to the oxygenic photosynthetic bacteria that cover the groups Cyanobacteria and Prochlorales. These photosynthetic organisms were first considered to be algae, a very large and diverse group of eukaryotic organisms, until 1962 when they were reclassified as prokaryotes and named Cyanobacteria. This designation was accepted and pu ...

Spirulina (suborder)

Spirula
''Spirula spirula'' is a species of deep-water squid-like cephalopod mollusc, mollusk. It is the only extant taxon, extant member of the genus ''Spirula'', the Family (biology), family Spirulidae, and the order (biology), order Spirulida. Because of the shape of its internal shell, it is commonly known as the ram's horn squid or the little post horn squid. Because the live animal has a light-emitting organ, it is also sometimes known as the tail-light squid. Live specimens of this cephalopod are very rarely seen because it is a deep-ocean dweller. The small internal shell of the species is, however, quite a familiar object to many beachcombing, beachcombers. The shell of ''Spirula'' is extremely light in weight, very buoyant, and surprisingly durable; it very commonly floats ashore onto tropical beaches (and sometimes even temperate beaches) all over the world. This seashell is known to Conchology, shell collectors as the ram's horn shell or simply as ''Spirula''. Description ...

Spiralinella
''Spiralinella'' is a genus of very small sea snails, pyramidellid gastropod mollusks, or micromollusks.Gofas, S.; Rosenberg, G. (2015). Spiralinella Chaster, 1901. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=743286 on 2015-04-06 Nomenclature Both this genus and its type species have had a very complicated synonymy. The status of the generic name ''Spiralinella'' in contrast to the names ''Partulida'' and ''Spiralina'' was clarified by Corgan (1973), and the nomenclatorical problems around the type species were discussed by van Aartsen & Gianuzzi-Savelli (1991). Life habits Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae ''sensu lato'', they are most likely to be ectoparasites. Species Species within the genus ''Spiralinella'' include: * '' Spiralinella incerta'' (Milaschewich, 1916) * '' Spiralinella marthinae'' (Nofroni & Schander, 1994) * '' Spira ...
