Centipedes have an exoskeleton, which is a hard, protective outer covering that provides support and protection for their bodies. The exoskeleton is made of a tough, chitinous material and covers the entire body of the centipede, including their legs, head, and antennae. The exoskeleton also helps to prevent water loss and provides a surface for the attachment of muscles. Unlike animals with an endoskeleton (such as humans), the exoskeleton of centipedes does not grow with them, so they must molt or shed their old exoskeleton in order to grow.
