Prokaryotes fall into three basic categories based on their shape, visualized here using scanning electron microscopy: (a) cocci, or spherical (a pair is shown); (b) bacilli, or rod-shaped; and (c) spirilli, or spiral-shaped.

Members of the genus Spirillum are characterized by a G+C content of about 38 mol% and are commonly found in freshwater environments (with the exception of S. minus). Like all the other Spirilla bacteria, all members of this group are Gram-negative.
