    A natural toroidal microswimmer with a rotary eukaryotic flagellum

    We describe Idionectes vortex gen. nov., sp. nov., a unicellular microeukaryote that swims by continuous inversion of its surface, similar to a vortex ring. This previously unreported mode of motility approximate...

    Apusomonadida

    Apusomonadida is a small group of free-living heterotrophic flagellates. Apusomonads are small (~5–20 μm long) gliding aerobes with two flagella. The dorsal cell membrane is underlain by a pellicle, which also...

    Euglenida

    Euglenids are a group of >1500 described species of single-celled flagellates with diverse modes of nutrition, including phagotrophy and photoautotrophy. The group also encompasses a clade of specialist “prima...

    Heterolobosea

    Heterolobosea is a group of ~150 described species of heterotrophs, almost all free living. Many are “amoeboflagellates” with a three-phase asexual life cycle, centered on trophic amoebae that can reversibly t...

    Protist Diversity and Eukaryote Phylogeny

    The last quarter century has seen dramatic changes in our understanding of the phylogenetic relationships among protist groups and their evolutionary history. This is due in large part to the maturation of mol...

    Jakobida

    Jakobida is a small group (<20 described species) that is related to Heterolobosea and Euglenozoa. Jakobids are free-living heterotrophs with two flagella. They primarily eat prokaryotes that are captured by s...
