Chilomonas (kai-low-moan-ass), one of the two genera of cryptomonad flagellates which do not have chloroplasts. There are two flagella which insert into a groove which opens subapically (the dent near the front of the cell is where is opens). Cytoplasm with large numbers of polysaccharide granules. Differential Interference Contrast.

There are two flagella which insert into a groove which opens subapically (the dent near the front of the cell is where is opens). Special extrusomes (ejectisomes) form a little cluster around the flagellar pocket (the pocket can not be seen). Cytoplasm with large numbers of polysaccharide granules. This cell slightly distorted. Differential Interference Contrast.

Chilomonas (kai-low-moan-ass), one of the two genera of cryptomonad flagellates which do not have chloroplasts. There are two flagella which insert into a groove which opens subapically - the flagella can be seen here as the two dark filaments emerging from the anterior (top) of the cell. Cytoplasm with large numbers of polysaccharide granules. Phase contrast.

Chilomonas paramecium Ehrenberg, 1831. Colourless cryptomonads, with stiff elongate-ovate body, 19 to 30 microns long. Two subequal flagella, shorter than the length of the body, insert in an anterior pocket which is surrounded by rows of extrusomes. Small extrusomes are also visible under the cell membrane. The nucleus is located posteriorly to the pocket. A contractile vacuole is located anteriorly and empties into the pocket. Cells contain refractile storage products and often two refractile Maupas bodies. Cells rotate while swimming, and can also swim backwards.
