The apusomonads (family Apusomonadidae) are a group of protozoan zooflagellates that glide on surfaces, and mostly consume prokaryotes. They are of particular evolutionary interest because they appear to be the sister group to the Opisthokonts, the clade that includes both animals and fungi. Together with the Breviatea, these form the Obazoa clade.[3][4][5]
Characteristics
Apusomonads are small
- Derived cell plan, represented by Apusomonas, with a round cell body and a mastigophore, a projection of the cell containing both basal bodies at its end.[6]
- "Amastigomonas-like" cell plan, with an oval or oblong cell that generally forms
