| Species | |
Pteridomonas is a genus of heterotrophic flagellates belonging to the phylum Ochrophyta. It was described in 1890 by Eugène Penard. Species of this genus descend from a group of photosynthetic algae but have secondarily lost their chloroplasts. They are single-celled flagellates, attached to the substrate by a stalk and distinguished by a ring of tentacles around the single flagellum. They can be found in marine, brackish or freshwater environments.
