Collodictyonidae

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. It's one of the three groups of the so proposed clade GRiDi, the others being glissandrids and rigifilids.^[2]
