Percolomonas (perk-o-low-moan-ass) is an excavate flagellate - in that it has a ventral groove or gutter that is used in feeding, and is usually classified with the heterolobosea. Two to four flagella insert at the head of the groove, one (the recurrent flagellum) is much longer than the others. Often found in slightly smelly (i.e. anoxic) habitats. Differential interference contrast.

Bodo rostratus (Kent, 1880) Klebs Bodo cells that are about 8.5 microns long. Cell elongate-ovate, somewhat inflated posterioly, the anterior end pointed and usually slightly recurved towards the ventral aspect, flagella equally slender, the anterior vibratile flagellum from one and a half to twice the length of the body, the posterior one longer than the proceeding, contracting, when the cell is attached, in a loose spiral coil, contractile vacuole mostly conspicuous, situated close to the anterior end, nucleus located near the opposite or posterior end.

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).

Colacium (coal-ace-ee-um) is a euglenid flagellate in which the cells are attached to the substrate b y means of a mucoid stalk. the euglenids are attached to the stalks by their anterior region. As in this species, the stalks may branch and form moderately large aggregates. The individual cells may break free from the stalks and swim away, at which time they are indistinguishable from members of the genus Euglena. Phase contrast.

Bodo (Boe-dough) platyrhynchus Larsen and Patterson, 1990. Cells are about 5 to 9 microns long, dorso-ventrally flattened and slightly flexible. The anterior margin of the cell is flattened. Cell outline is ovoid and two flagella insert subapically. The anterior flagellum is shorter than the cell and beats stiffly from side to side. The trailing posterior flagellum is about twice the length of the cell and is acronematic. The cells glide slowly with a waggling movement, but may more rarely swim with a slow rotating movement. Rarely observed.

From snails, phase contrast showing the anterior flagellum and the recurrent adhering flagellum.

Cyclidiopsis (sigh-clid-ee-op-sis) is a colourless heterotrophic euglenid, but is unusual in that it has an eyespot seen just below the vacuole-like reservoir. The refractile elements inside the cell are polysaccharide storage granules (paramylon) Elongate, anterior slightly trumpet-like with one emergent flagellum. Not often encountered. Differential interference contrast.

Percolomonas (perk-o-low-moan-ass) is an excavate flagellate - in that it has a ventral groove or gutter that is used in feeding, and is usually classified with the heterolobosea. Four flagella insert at the head of the groove. They insert in parallel. Often found in slightly smelly (i.e. anoxic) habitats. Phase contrast.

Cyclidiopsis (sigh-clid-ee-op-sis) is a colourless heterotrophic euglenid, but is unusual in that it has an eyespot. Elongate, anterior slightly trumpet-like with one emergent flagellum. Not often encountered. This is a dividing cell. Phase contrast.
-
Percolomonas cosmopolitus (Ruinen, 1938) Larsen and Patterson, 1990. Obovate cell, 6-10microns long, with a ventral groove arising subapically and extending half the length of the cell. Four flagella insert subapically: one approximately twice the length of the cell, extending behind the cell, used for adhesion to substratum: three shorter flagella lie within the groove and are used to creat a current of water from which suspended particles are extracted. Nucleus anterior, with globular nucleolus.

Bodo designis (beau-dough), small flagellate, with two flagella, moving with a rotating motion, skipping or gliding motion. One of the most common of the bodonids, found in almost every habitat so far studied. Moves by skipping near surfaces. It stops to ingest attached or detrital bacteria with the anterior mouth (in the rostrum). Phase contrast, rotten picture.

Dientamoeba is an amoeboid and amastigote parabasalid of about 5-20 µm in diameter, containing v-shaped parabasal body close to the nucleus but no flagella and axostyle. In binucleate cells a paradesmose is stretched between the two polar centers at the origin of the parabasal fibers. Anaerobic, contains hydrogenosomal granules, moves by amoeboism and phagocytoses particles such as bacteria and inhabits the intestine of humans. Dientamoeba fragilis, phase contrast.

Cyclidiopsis (sigh-clid-ee-op-sis) is a colourless heterotrophic euglenid, but is unusual in that it has an eyespot. Elongate, anterior slightly trumpet-like with one emergent flagellum. This image is to show the beat pattern of the flagellum. Not often encountered. Phase contrast.

Monocercomonas are small trichomonad flagellates (5-15 µm) with three anteriorly directed flagella and a recurrent one slightly adhering on its proximal part to the cell body. Well developed axostyle protruding posterioly. Parabasal body rod-, disc- or V-shaped. About 20 species occurring in the intestinal tract of vertebrates such as M. caviae from the caecum of guinea pigs (Nie 1950) or invertebrates such as termites, roaches, tipulid larvae. Unidentified species from the gut of the cockroach Parasphaeria boleiriana from Brazil (interference contrast)

Bodo designis, small flagellate, with two flagella, moving with a rotating motion, skipping or gliding motion. The flagella insert into a small subapical pocket, as is suggested by the subapical depression. One of the most common of the bodonids, found in almost every habitat so far studied. Moves by skipping near surfaces. It stops to ingest attached or detrital bacteria with the anterior mouth (in the rostrum). Phase contrast
