How many pairs of legs do millipedes typically have?

Millipedes are known for their unique body structure, which consists of multiple segments. Each segment typically bears two pairs of legs. This characteristic is what leads to the term "millipede," which means "thousand feet" in Latin, though not all millipedes have exactly a thousand legs.

They usually have a significant number of legs overall, often ranging from around 30 to over 400, depending on the species. The presence of two pairs of legs per body segment allows for the millipede's distinctive movement and ability to navigate through various environments.

In contrast, the other options provide incorrect quantities that do not accurately represent the anatomy of millipedes, as they possess many more legs than just one, two, or three pairs. Thus, multiple pairs is the only option that accurately reflects the typical leg configuration found in millipedes.
