Many archaea display swimming motility in liquid medium, which is empowered by the archaellum. Directional movement requires a functional archaellum and a sensing system, such as the chemotaxis system that is used by Euryarchaea. Two well-studied models are the euryarchaeon Haloferax volcanii and the crenarchaeon Sulfolobus acidocaldarius. In this chapter we describe two methods to analyze their swimming behavior and directional movement: (a) time-lapse microscopy under native temperatures and (b) spotting on semi-solid agar or gelrite plates. Whereas the first method allows for deep analysis of swimming behavior, the second method is suited for high throughput comparison of multiple strains.
