Most recent taxonomic treatment adopted: Throndsen, J. (1996). The planktonic marine flagellates. In: Identifying marine phytoplankton. (Tomas, C.R. Eds), pp. 591-730. San Diego: Academic Press.
Saline, aquatic habitats and hypersaline soil; 2 palmelloid isolates grew as well in freshwater as in highly saline media (Buchheim et al. 2010). - (5 Nov 2010) - Wendy Guiry
Description: Unicellular,biflagellate and uninucleate algae without cellulosic cell walls, oftenwith considerable metaboly. Cells fusiform, ellipsoid, ovoid, obovoid,globose or depressed-globose. Anterior end usually rounded or slightlyacuminate; posterior end rounded, or in some cases, caudate. Chloroplastparietal and principally cup-shaped; pyrenoid and stigma present orabsent. Nucleus typically in anterior end along with two contractilevacuoles, these may be quite indistinct in freshwater. Cytoplasmicorganization may be masked by accumulations of haematochrome pigment.Asexualreproduction by cell division sometimes giving rise to a palmelloid stage;occasionally cells become encysted. Sexual reproduction by fusion ofisogametes; zygote typically thin walled, occasionally ornamented. Upongermination, 4-8(-16) zoospores released.

Comments: Dunaliella spp. widely distributed in marine or brackish waterhabitats. Four species, D. acidophila (Kalina) Masjuk, D. carpaticaMasjuk, D. lateralis Pascher et Jahoda and D. pauperaPascher, may be found in freshwater or slightly brackish habitats; otherspecies, notably D. salina and D. viridis Teodoresco, may befound in inland salterns and brine lakes.
Numbers of names and species: There are 29 species names in the database at present, as well as 3 infraspecific names. Of the species names, 26 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..
Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.
Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
