Videos of moving microbes
Movement by microorganisms in water is very different from that of humans and other large animals due to the overwhelming effects of viscosity at small size scales.
Microbial swimming (equivalent to humans swimming in molasses) requires special techniques. Successful techniques are the ‘flexible oar’ (cilium), the ‘corkscrew’ (forward facing flagellum) and cellular deformation.
