Ancyromonas (an-kire-o-moan-ass), gliding flagellate. With one flagellum extends posteriorly. the other is absent or very fine, and can be seen emerging from an anterior depression in the cell. Very widespread and common, seems to occur almost anywhere where there is water and food. Phase contrast, rotten picture. This picture was taken by David Patterson and Michele Burford of material from a commercial prawn farm in Queensland, Australia in 2000. Image copyright: D. J.

|Description of Ancyromonas sigmoides: The cell outline is oval. Cells are 3 to 7 microns long, 2 to 3.5 microns wide and dorso-ventrally flattened. This species has a shallow groove ventrally near an anterio-lateral margin of the cell. The cells have a thin stiff anterior flagellum emerging from an anterior depression. The anterior flagellum can be easily overlooked and beats slowly. The posterior flagellum is about 1.5 times the length of the cell and may not be acronematic. The cells move by gliding with the posterior flagellum trailing. |
