Goniomonas (go-knee-o-moan-ass) is one of two genera of cryptomonads without chloroplasts. The other is Chilomonas. Goniomonas (also incorrectly called Cyathomonas in some of the literature) is unlike all other cryptomonads because it is primitively aplastidic, and because there is no deep pocket inside the cell. The homologue is located running parallel to the front margin of the cell, and is associated with a line of extrusiible bodies. With two flagella emerging from one anterior corner of the cell. Very flattened. Common but small. Differential interference contrast.

Goniomonas (go-knee-owe-moan-ass) is a small cryptomonad flagellate. Typically flattened, with two flagella (not visible here) emerging from a pocket located near one of the anterior corners of the cell. The refractile region is a band of extrusomes. Phase contrast. Material from Nymph Creek and Nymph Lake, thermal sites within Yellowstone National Park, photograph by Kathy Sheehan and David Patterson.

Goniomonas, often referred to as Cyathomonas, a colourless cryptomonad. Known to occasionally consume bacteria. Two flagella insert in a small pocket to one siode of the flattened anterior end of the cell. There is a line of refractile ejectisomes running parallel to the front edge of the cell. From Lake Donghu, China. Phase contrast micrograph.

Goniomonas, a small heterotrophic cryptomonad. the shape is not typical of other members of the group. It is flattened , the front end looks as if it has been cut off. Two flagella arise from one corner of the front of the cell. There is a short line of ejectisomes (extrusomes) running parallel to the front edge fo the cell. From a freshwater pond near Boise, Idaho.

Goniomonas (gop-knee-owe-moan-ass) amphinema. Larsen and Patterson, 1990. Cells are 3 - 9 microns long. Two flagella insert in an anterior lateral pocket, one directed anteriorly, one posteriorly. The two flagella are unequal in length. The long flagellum usually trails over the body and is slightly longer than the cell. The cells are flattened with anterior row of ejectisomes and with or without several longitudinal ridges. The row of ejectisomes is at times difficult to observe. Commonly observed.

Goniomonas (go-knee-owe-moan-ass) pacifica Larsen and Patterson, 1990. Cells are 4 to 10 microns long and with several distinct longitudinal ridges on both sides of the cell. There is a row of about seven to nine ejectisomes near the anterior end of the cell, which is truncated with the posterior end rounded. Two flagella of similar length emerge from a small anterior depression and are directed anteriorly. When the cells are swimming, two flagella diverge in different directions. Less common than G. amphinema in marine sites.
