black and white portrait
Bordnamonas (board-na-moan-ass) tropicana - the orientation of the two flagella is characteristic of swimming cells. The apical mouth is visible. This picture was taken by Won Je Lee using conventional photographic film using a Zeiss Axiophot microscope of material collected in marine sediments of Botany Bay (Sydney, Australia). The image description refers to material from Botany Bay. Image copyright: Won Je Lee, image used under license to MBL (micro*scope).

|Description of Bordnamonas tropicana: Cells are 4 to 11 microns long, 2.5 to 4 microns wide, flattened, and flexible, particularly when squashed. The cells are anteriorly narrow and posteriorly broad. Two slightly thickened flagella, similar in length, insert subapically in the right ventral side of the cell and are approximately 1.5 times the length of the cell. The flagellar are not acronematic. The anterior flagellum beats stiffly and is held in a sigmoid arc, and the posterior flagellum curves near its flagellar insertion and is directed towards the rear of the cell. An apical mouth is visible by light microscopy. The cells move by gliding or rapidly by skidding close to the substrate. |
