Ciliated protozoan (Tetrahymena vorax), coloured scanning electron micrograph (SEM). Tetrahymena vorax is a fresh water, holotrichous, oligohymenophoran, ciliate. Shown here are 3 cells with nice ciliated pellicle surfaces. Tetrahymena are free-living ciliated protozoa that can switch from commensalistic to pathogenic modes of survival. They are common in freshwater ponds. Tetrahymena species are used as model organisms. Magnification: x260 when shortest axis printed at 25 millimetres.
