Bodo (boe-dough) saliens Larsen and Patterson, 1990. Cells are usually elongate elliptical and somewhat inflexible, and are 4 to 12 microns long (mostly 6 to 9 microns). Two flagella unequal in length emerge subapically from a shallow pocket. The anterior flagellum appears inactive, is as long as or slightly shorter than the cell and is held forwards with a single anterior curve held perpendicular to the substrate. The acronematic posterior flagellum is typically directed straight behind the cell and is about 2.2 to 3.5 times cell length. The cells swim in rapid darts in straight lines. Frequently observed. Description based on observations of 43 cells.

Cruzella marina De Faria et al., 1922. Cells metabolic, about 27.5 microns, spindle-shaped or oval, slightly compressed on the sides, with sharp-pointed posterior end, when anterior end is terminated by a long snout. The anterior flagellum is shorter than the trailing flagellum, it is equal to the body length and it emanates from the end of the snout. The trailing flagellum emanates just below the snout and is twice the body length. The contractile vacuole not described. Nuclues in the centre.

Portrait of the colorless euglenoid flagellate, Menoidium bibacillatum (Pringsheim, 1942). Strongly flattened. One side curved with the other more straight. One emergent flagellum. Stigma absent. Paramylon bodies are dimorphic with smaller round and larger elongate ring forms. Swims rotating on long axis. Highly refractile. From standing freshwater near Boise, Idaho. DIC.

Cryptobia are monogenetic (single host) bodonid flagellates with an anteriorly directed flagellum and a recurrent flagellum attached along the entire length of the body, but does not form a prominent undulated membrane. The cytostome is situated far from the flagellar pocket but is linked to it by a prominent preoral ridge. The cell bears a kinetoplast at the base of the flagella. All are parasitic or endo-commensals in host cavities such as reproductive system of gastropods, the gut of fishes. This species, Cryptobia helicis, is from the seminal receptacle of Helix - a snail, contracted and elongated form with the anterior kinetoplast close to the nucleus, the anterior free flagellum and the recurrent adherent flagellum (Giemsa).

Scale bar indicates 10 µm. Sample from the pond Hegne Moor situated in the vicinity of Lake Constance. The image was built up using several photomicrographic frames with manual stacking technique. Images were taken using Zeiss Universal with Olympus C7070 CCD camera.Image under Creative Commons License V 3.0 (CC BY-NC-SA).

Distigma (die-stig-ma), heterotrophic euglenid flagellate. There are two flagella which are attached to the cell in a flagellar pocket which is an invagination that leads to the front of the cell by a tube called the flagellar canal. The light disc near the front is the contractile vacuole which is located alongside the flagellar pocket which cannot be seen in this image. One flagellum is long, the other short. The cytoplasm has large amounts of paramylon granules. The cell can squirm (is metabolic). Phase contrast.
