All centipedes have an odd number of body segments, and each segment has two legs attached to it. After the full complement of legs is achieved, the now postlarval stadia (about five stages) develop gonopods, sensory pores, more antennal segments, and more ocelli. They also bear long and multi-segmented antennae. The number of leg-bearing segments varies widely, from 15 to 191, but the developmental mode of their creation means they are always added in pairs—hence the total number of pairs is always odd.
