Carnivorous ciliates

Carnivorous ciliates

Also known as suctoria, these microorganisms transform the eyelashes in structures similar to spines located at the vertex. On the approach of a prey, these hard tentacles prick the cell and feed on its contents. In adult stage live attached to the biological floc through a stalk, and when young have free life. In activated sludge systems indicate stability and high OD due to the fact that they are very sensitive to operating changes.
