black and white portrait
Jenningsia (jen-ings-ee-a) macrostoma (Ekebom et al., 1996) Lee et al., 1999. Cells are about 80 - 114 microns, anteriorly narrowed or pointed and posteriorly rounded, and very metabolic. With fine pellicular striations following an S-helix and with the ingestion organelle that has two well-marked rods is strongly developed. Ventral striations are more distinct than the dorsal ones. The flagellar pocket is situated on the left ventral face of the cell. The flagellum is as long as the cell and beats freely. There is a refractile arc-like structure associated with the slit-like opening of the flagellar canal. Refractile granules are randomly distributed inside the cell. The nucleus is situated in the posterior end of the cell. The cells glide with a squirming movement. Rarely observed. 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).
