WebCollective motion of flagella has long been observed in cells. For example, in bacteria with multiple flagella, flagella can rotate in a helical fashion and form a bundle [1,2]. In mammalian sperm, cells have a single flagellum but flagellar motion may be impacted by neighboring sperm or other structures in the environment. The three types of flagella are bacterial, archaeal, and eukaryotic. The flagella in eukaryotes have dynein and microtubules that move with a bending mechanism. Bacteria and archaea do not have dynein or microtubules in their flagella, and they move using a rotary mechanism. Other differences among these three types are:
