Filamoeba cf. nolandi, copyright Protist Information Server.

Belongs within: Eukaryota.
Contains: Tubulinea, Discosea, Mycetozoa, Archamoebae.

The Amoebozoa is a clade of primarily unicellular eukaryotes in which most members have an amoeboid stage in their life cycle; some are exclusively amoeboid.

See also: TAFKAMI; TAFKAMI walks; Amoebozoan classification: putting the formless in formation; Amoebozoan oddments.

Characters (from Adl et al. 2012): Cells “naked” or testate; tubular mitochondrial cristae, often branched (ramicristate), secondarily lost in some; uninucleate, binucleate or multinucleate; cysts common, morphologically variable; sexual or asexual; many taxa exhibit either sporocarpic (single amoeboid cell differentiates into a usually stalked, subaerial structure that supports one to many propagules termed spores) or sorocarpic (amoebae aggregate into a multicellular mass that develops into a multicellular fruiting body) fruiting; or myxogastroid ciliated stages; when amoeboid, locomotion with noneruptive morphologically variable pseudopodia; ancestrally bikont with many taxa exhibiting reduction of the bikinetid.
