How many pairs of legs do millipedes have per body segment?

  1. One pair

  2. Two pairs

  3. Three pairs

  4. Four pairs

The correct answer is: Two pairs

Millipedes are distinct in that they possess two pairs of legs per body segment. This characteristic is one of the key features that differentiate them from other arthropods, such as centipedes, which have one pair of legs per body segment. The presence of two pairs of legs enhances their locomotion and allows for more stability as they move through their environment. Every segment of a millipede body, except for the first few which may have reduced limbs, contributes to this dual pairing. This anatomical structure is a factor that plays a role in their overall biological classification within the millipede class, Diplopoda. Understanding this feature is important for pest control technicians who may need to identify various arthropods.
