These bacteria very rarely have flagella:

Explanation

Cocci bacteria, which are characterized by their spherical or ovoid shape, typically do not have flagella. Flagella are long, whip-like appendages that bacteria use for motility. Instead, cocci bacteria usually lack flagella and rely on other means of locomotion or remain non-motile. Their small, rounded shape is not conducive to the typical spiral or rod-shaped bacteria with flagella that use these structures for movement.
