"Singing" Bacterium, Swimming Algae - What a Wonderful World...

"...Recent observations of Synechococcus using atomic force microscopy show these creatures having tiny spikes or spicules that extend from the cell's inner membrane, out through a crystalline outer shell and into the surrounding water.
Ehlers and co propose that these spicules can be made to vibrate by molecular motors within the cell and that this vibration causes nearby fluid to flow, generating movement (a phenomenon called acoustic streaming).

In effect, the bacteria "sing" themselves along."
