Description: Oscillatoria is a genus of unbranched filamentous cyanobacteria with mucilaginous sheaths. The genus is named for its oscillating movement; filaments can slide back and forth in order to orient the colony towards a light source. Oscillatoria can produce both anatoxin-a and microcystins.

Synonym: Oscillatoria is closely related to the genera Planktothrix, Limnothrix, Tychonema, and Trichodesmium.
