Abstract
It is observed that the Navier-Stokes rescaling invariance , , shows up in the chemotaxis of motile . coli and the phototaxis of . uncinatum. Quantitatively accurate measurements on other motile bacteria and blue-green algae may reveal that this underlying hydrodynamic symmetry is featured commonly in the tactic migration of micrometer-size organisms in aqueous media.
