What shape do spirilla bacteria resemble?

Spirilla bacteria are characterized by their distinctive spiral or corkscrew shape. This morphology is crucial as it influences their movement and behavior. The hair-like structures called flagella, which may be present in some spirilla, allow these bacteria to move in a twisting or corkscrew motion, effectively enabling them to navigate through viscous environments. This shape is quite different from other bacterial forms, such as cocci (round) or bacilli (rod-shaped), which have their own unique characteristics and functions. The specific shape of spirilla contributes to their adaptability and survival in various ecological niches, which is essential for understanding their role in different environments.
