The amoebozoa are one of several groups of eukaryotes . They only include unicellular organisms.

features

All members of the Amoebozoa are unicellular organisms that are usually characterized by an amoeboid shape. The morphologically variable cells can be naked or, as in the Thecamoebida (Thecamoebida), wired. The cristae of the mitochondria are mostly tubules that are often branched or have been reduced in some groups ( taxa ). Most species have only one nucleus , but others can have two or more. In addition, cysts and cell inclusions such as parasomes and trichocysts are not uncommon and are used as a distinguishing feature . Flagellated stages of development usually have only one flagellum , an original feature are two flagellae. The amoeba reproduce by dividing two or more times. Some species also have sexual reproduction. Numerous groups, especially Myxogastria and Dictyostelia with ( Dictyostelium discoideum ), form multinucleated cell aggregates without ( Plasmodium ) or with (pseudoplasmodia) membranes between the individual cells, which can reach macroscopic dimensions.

Systematics

The Amoebozoa are, along with the Opisthokonta (which include animals and fungi), one of the two large groups that together with some smaller taxa form the Amorphea . The Amoebozoa are divided into the following groups:

Tubulinea Smirnov et al. 2005
Discosea Cavalier-Smith et al. 2004
Archamoebae Cavalier-Smith 1983
Gracilipodida Lahr et al. 2011
