What is the shape of the oscillatoria?

Oscillatoria is a genus of filamentous cyanobacteria that typically forms long, unbranched, and often twisted filaments. These filaments consist of cylindrical cells arranged end-to-end, giving them a ribbon-like appearance. The cells can vary in length and may display a greenish or bluish coloration due to the presence of chlorophyll. Overall, their shape is elongated and flexible, allowing them to move with water currents.
