Phase contrast image showing two flagella of similar lengths inserting near the anterior pole of rhc ell. The light area posterior to the point of flagellar insertion is the nucleus. This flagellate eats bacteria - such as those around it.

Cercomonas (sir-ko-moan-ass), gliding flagellates, two flagella insert just below the anterior apex of the cell. The anterior flagellum beats floppily, the posterior flagellum trails against the substrate. Body very flexible and elements may be drawn out as strands behind the moving cells. Common. Lots of species, but the taxonomy is very unstable. The very light region is the contractile vacuole. Phase contrast.

This amoeba with filamentous pseudopodia looks like Lecythium spec. Sample from a pond on the island of Hiddensee (Baltic Sea, Germany). This image was taken using Zeiss Universal with Olympus C7070 CCD camera.

Cryothecomonas (cry-oh-theek-oh-moan-ass) is a medium-sized heterotrophic flagellate with two similar flagella emerging from a point just behind the apex of the cell. The ventral surface is grooved (and this causes a slight indentation at the front of the cell). Pseudopodia may arise from the ventral groove. They consume diatoms and other detritus. Phase contrast microscopy.

Chlorarachnion (clore-a-rack-knee-on) reptans, an unusual autotrophic amoeboid organism. The plastids were obtained by endosymbiosis from an alga, and a residual algal nucleus, referred to as a nucleomorph, provides genetic information for plastid activity. Cells often form extensive arrays with interconnected pseudopodia. This image shows a single cell with its pseudopodia. Differential interference microscopy.

Cercomonas (sir-ko-moan-ass), gliding flagellates, two flagella insert just below the anterior apex of the cell. The anterior flagellum beats from side to side, the posterior flagellum trails against the substrate. Body very flexible and elements may be drawn out as strands behind the moving cells. Common. Phase contrast.

Rhogostoma (row-gaw-stow-ma) is a rarely reported amoeba with a flexible surrounding test and with a small opening through which pseudopodia can emerge. The opening is at the bottom of the cell and looks as if it has two lips. Large nucleus with nucleolus at the other side of the cell. Eats bacteria. Phase contrast.
