flagella

Description:

Massisteria (mass-hysteria) is a cercomonad flagellate, with one species (M. marina ), measuring 2.5 to 6.5 microns, dorso-ventrally flattened irregular body. Cells produce delicate pseudopodia with extrusomes, which extend radially from the cell and normally adhere to the substrate. This image shows the two short curved flagella which arise from the dorsal side of the cell. The flagella are relatively inactive in trophic cells, and are very hard to see. Cells may withdraw pseudopodia, and swim using the flagella. Differential interference contrast.
