Breviata anathema is a single-celled flagellate amoeboid protist, previously studied under the name Mastigamoeba invertens. The cell lacks mitochondria., but has remnant mitochondrial genes, and possesses an organelle believed to be a modified anaerobic mitrochondrion, similar to the mitosomes and hydrogenosomes found in other eukaryotes that live in low-oxygen environments.

Early molecular data placed Breviata in the Amoebozoa, but without obvious affinity to known amoebozoan groups.More recently, Phylogenomic analysis has shown that the class Breviatea is a sister group to the Opisthokonta and Apusomonadida. Together, these three groups form the clade Obazoa.
