Bacteria can be classified based on various characteristics to better understand their diversity and behavior. One common method is by shape: cocci (spherical), bacilli (rod-shaped), and spirilla (spiral-shaped). They are also classified by their gram stain reaction—Gram-positive or Gram-negative—based on cell wall composition.

Oxygen requirements categorize bacteria as aerobic (requiring oxygen), anaerobic (not requiring oxygen), or facultative anaerobes (can survive with or without oxygen). Temperature preferences further divide them into psychrophiles (cold-loving), mesophiles (moderate temperature), and thermophiles (heat-loving). Additionally, bacteria are classified by their mode of nutrition, such as autotrophs (self-feeding) or heterotrophs (depend on other organisms).
