Oscillatoria (awe-sill-at-owe-ree-a) filamentous blue green alga (bacterium) common in sediments. Motile, without differentiated cells within the filament, but distinguished by a slight twist at the anterior end. Differential interference contrast.

-
Filamentous blue green algae with several morphologies, all lack a mucus sheath, glide and had no evident heterocysts (differentiated cells), and are probably (though not certainly) assignable to Oscillatoria. Phase contrast.
-
Oscillatoria (oss-sill-at-oar-ee-a) (tentative identification) upper filament with gas vacuoles - protein inclusions which are not easily distinguished from membrane bound compartments which distinguish eukaryotes. To get to a correct identification. care needs to be taken to check if ALL cells have the inclusions. Gas vesicles tend not to be present in all cells. Differential interference contrast.

Oscillatoria (oss-sill-at-oar-ee-ah) filamentous blue green alga *(cyanobacterium). Phase contrast.
-
Oscillatoria, a filamentous cyanobacterium, is able to glide over surfaces. These three images were taken over a period of about 2 minutes and show two filaments moving relative to each other.
-
Oscillatoria observed in freshwater sediments in the vicinity of Broome, Western Australia in September 2003. This image was taken using phase contrast optics. This work was supported by the Australian Biological Resources Study.

Two fine filaments of this cyanobacterium. Differential interference contrast optics.

Filaments of this blue-green alga (cyanobacterium). They glide slowly. Phase contrast microscopy.

Small region of mud with filaments of Oscillatoria forming a thin layer over the surface.
