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...

The other eukaryotes in light of evolutionary protistology
In order to introduce protists to philosophers, we outline the diversity, classification, and evolutionary importance of these eukaryotic microorganisms. We argue that an evolutionary understanding of protists...

Halocafeteria seosinensis gen. et sp. nov. (Bicosoecida), a halophilic bacterivorous nanoflagellate isolated from a solar saltern
Recently, heterotrophic nanoflagellates (HNF) have been reported to actively ingest prokaryotes in high salinity waters. We report the isolation and culture of an HNF from a Korean saltern pond of 300‰ salinit...

Ultrastructure and identification of the predatory flagellateColpodella pugnax Cienkowski (Apicomplexa) with a description ofColpodella turpis n. sp. and a review of the genus
A flagellated predator of the chlorophyte algaDunaliella spp. was examined by light and electron microscopy. Although this predator had previously been identified as a species of the kinetoplastid genusBodo, the ...
