Do chelicerata molt to grow

Yes, chelicerates, which include arachnids like Spiders and scorpions, do molt to grow. They undergo a process called ecdysis, where they shed their exoskeleton to allow for growth. This process is essential because their hard exoskeleton does not expand, necessitating periodic molting to accommodate their increasing size. After molting, they often need time to harden their new exoskeleton before they can resume normal activities.
