An order of the class Phytamastigophorea, also known as the Cryptomonadina. Cryptomonads are considered to be protozoa by zoologists and algae by botanists. Most species occur in freshwater. They are olive-green, blue, red, brown, or colorless. All flagellated members have two subequal flagella inserted in a gullet opening through an obliquely truncate anterior end (see illustration). In Nephroselmis and Protochrysis the gullet is laterally displaced and a contractile vacuole opens into it. The nucleus is posterior. Oil and starch or a related compound are formed and pyrenoidlike bodies are present. Cyathomonas and Chilomonas are colorless; the latter has been widely used in nutritional studies, and extensive studies have been made of its cytology, demonstrating trichocysts around the gullet and muciferous bodies under the pellicle.
