'''''Ankyra''''' is a [genus](/source/genus) of [green algae](/source/green_algae) in the family [Characiaceae](/source/Characiaceae).<ref name="AlgaeBase"/> This genus of algae is closely related to ''[Atractomorpha](/source/Atractomorpha_(alga))'' and ''[Sphaeroplea](/source/Sphaeroplea)''.<ref>{{cite journal |vauthors = Buchheim MA, Michalopulos EA, Buchheim JA |name-list-style=amp|title=Phylogeny of the Chlorophyceae with special reference to the Sphaeropleales: a study of 18S and 26S rDNA data. |journal=Journal of Phycology |year=2001 |volume=37 |issue=5 |pages=819–835 |doi=10.1046/j.1529-8817.2001.00162.x|bibcode=2001JPcgy..37..819B |s2cid=84617219 |doi-access=free }}</ref> They are found in stagnant waters.<ref name=Krienitz>{{cite journal | doi=10.1007/s10750-012-1079-z| title=Present state of the systematics of planktonic coccoid green algae of inland waters| date=2012| last1=Krienitz| first1=Lothar| last2=Bock| first2=Christina| journal=Hydrobiologia| volume=698| issue=1| pages=295–326| bibcode=2012HyBio.698..295K| s2cid=254551673}}</ref>

''Ankyra'' consists of single cells that are [planktonic](/source/planktonic) or [epiphytic](/source/epiphytic). Cells are spindle-shaped or cylindrical with the ends tapering into long spines. At one end, the spine is bifid and/or enlarged into a spatula-like appendage. The [cell wall](/source/cell_wall) consists of two pieces that are joined together at the middle of the cell. One band-shaped [chloroplast](/source/chloroplast) lines the inside of the cell membrane, and contains a single [pyrenoid](/source/pyrenoid).<ref name=Bicudo_and_Menezes2006>{{cite book | title= Gêneros de Algas de Águas Continentais do Brasil: chave para identificação e descrições | edition=2 | year=2006 | first1=Carlos E. M. |last1=Bicudo | first2=Mariângela | last2= Menezes | publisher= RiMa Editora | pages=508 | isbn= 857656064X }}</ref>

Reproduction occurs via [zoospore](/source/zoospore)s which are released when the two halves of the cell wall break apart, or through a hole formed in the cell wall. Sexual reproduction has not been observed in ''Ankyra''.<ref name=AlgaeBase>{{AlgaeBase genus|id=43378|name= Ankyra|access-date=2023-12-16}}</ref> However, various [aplanospore](/source/aplanospore)-like stages and other resting stages have been observed in ''Ankyra'', and need to be studied further.<ref name=Krienitz/>

Species are identified based on the shape of the cells and their appendages.<ref name=AlgaeBase/>
