What is the common characteristic of the body structure in chilopods?

The common characteristic of the body structure in chilopods, which includes centipedes, is their elongated and flattened bodies. Chilopods exhibit a distinct body plan that consists of multiple segments, each typically bearing one pair of legs. This segmentation contributes to their agility and ability to move swiftly through various environments. The elongated form aids in their predatory lifestyle, allowing them to navigate efficiently in search of prey, such as insects and other small organisms.

The flattened aspect of their bodies enhances their ability to maneuver in tight spaces, which is advantageous for avoiding predators and ambushing their prey. Therefore, the choice emphasizing an elongated and flattened structure accurately describes these creatures and their adaptations.
