No, spiders do not have bones. Spiders, like all arachnids and insects, have an exoskeleton. An exoskeleton is a hard, protective, outer shell that supports the body, provides a defensive shield, and allows for movement through the use of attached muscles.

This is different from an endoskeleton, which is the internal skeleton structure that humans and many other animals have. Bones are a part of an endoskeleton. Spiders do not have an internal skeletal structure, so they don’t have bones. Their hard exoskeleton provides the support and structure that bones provide in animals with endoskeletons.
