The legs of a vertebrate are typically composed of bones, muscles, and connective tissue, and are used for locomotion. In contrast, the legs of an invertebrate are typically composed of a hard exoskeleton, and are used for both locomotion and protection. Vertebrate legs are typically jointed, allowing for greater flexibility and range of motion, while invertebrate legs are typically rigid and immobile. Vertebrate legs are typically used for walking, running, and jumping, while invertebrate legs are typically used for crawling, climbing, and swimming. Vertebrate legs are typically adapted for terrestrial locomotion, while invertebrate legs are typically adapted for aquatic or aerial locomotion.
