Here's a little more about them:

* Shape: Spirilla are characterized by their rigid, helical (spiral) shape.

* Size: They are generally larger than other bacteria, measuring around 0.5-2.0 micrometers in diameter and 10-100 micrometers in length.

* Movement: Some spirilla are motile, meaning they can move. They achieve this through flagella, whip-like structures that extend from their bodies.

* Examples: Notable examples of spirilla include *Campylobacter jejuni* (causes food poisoning) and *Treponema pallidum* (causes syphilis).
