Breviata anathema is a single-celled protist. It lacks mitochondria but has numerous differences with other amitochondiate Amoebozoa like Entamoeba and Endolimax.[1][2] Because B. anathema has genes which are known from mitochondria, it is likely to possess degenerate mitrochondria.[3] The closest relatives of B. anathema are not clear; molecular data places it in the Amoebozoa, but without obvious affinity to known groups of Amoebozoa.[3][4]
It has previously been studied under the name Mastigamoeba invertens.[5]
