Amastigomonas (a-ma-stig-o-moan-ass), a commonly encountered gliding flagellate from soils, freshwater and marine habitats., Cell enclosed in the dorsal lorica which makes the front flagellum seem thick. Recurrent flagellum lies under the cell and can be made out as a darker curving region. Phase contrast. Poor 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 Amastigomonas debruynei: Cells are 5 to 6.5 microns long, dorso-ventrally flattened and flexible but not amoeboid. The anterior flagellum emerges from the tip of a laterally directed sleeve and beats in a small angle. The posterior flagellum is slightly longer than the length of the cell, lies in a groove along the margin of the cell, trails under the cell and occasionally protrudes behind the cell. Strands of cytoplasm may be drawn out behind the cell. The nucleus is situated in the anterior left of the cell. |
