Which pair of legs arrangement is characteristic of the millipede?

The characteristic arrangement of legs in millipedes is indeed two pairs of legs per segment. This specific anatomical feature sets them apart from other similar arthropods. Millipedes belong to the class Diplopoda, which is known for this distinctive body structure. Each body segment of a millipede typically has two pairs of legs, which contributes to their unique locomotion. This arrangement allows for greater stability and movement as they navigate through their environments, often in leaf litter or soil.

Understanding this aspect is essential for accurately identifying millipedes and distinguishes them from other arthropods, such as centipedes, which have a different number of legs per segment. This knowledge is significant for anyone studying pest management and ecology within the context of the Kansas Pesticide Pro Exam.
