Collodictyonidae (also Diphylleidae) is a group of aquatic, unicellular eukaryotic organisms with two to four terminal flagella. They feed by phagocytosis, ingesting other unicellular organisms like algae and bacteria. The most remarkable fact of this clade is its uncertain position in the tree of life. A recent phylogenomic analysis places it either as sister group of the excavate protist Malawimonas or as sister group of the Bikonta clade, although both positions received considerably low branch support values.[1] This means that Collodictyonidae is somewhere near the root of the Eukaryote tree, probably close to the unikontbikont bifurcation.
