Millipedes possess a segmented body structure, which is a defining characteristic of their classification within the class Myriapoda. Their bodies are composed of numerous segments – each typically containing two pairs of legs – and this segmentation contributes to their flexibility and movement. This feature allows millipedes to burrow into soil and navigate through leaf litter effectively.

While options like a fluid-filled body, rigid exoskeleton, or flat body may pertain to other types of organisms, they do not accurately describe the physiological traits of millipedes. For instance, fluid-filled bodies are more commonly associated with organisms in different groups, such as jellyfish or certain other invertebrates. A rigid exoskeleton is a characteristic of arthropods such as insects and crustaceans, whereas a flat body can refer to organisms like flatworms. Thus, the segmented body structure is uniquely aligned with the biological classification and functional ecology of millipedes.
