    Spiders have exoskeletons:

    "A hard shell called an exoskeleton covers the entire body of a spider. The exoskeleton is made of cuticle, a material composed of a combination of protein and tough fibers called chitin. The cuticle forms thin layers stacked on top of one another, an arrangement that improves the strength and elasticity of the exoskeleton. The spider’s cuticle provides attachment sites for many muscles, and it also prevents desiccation (loss of body water). The cephalothorax cuticle is strong and stiff, while the cuticle of the abdomen is soft and extensible. As a spider grows, it sheds or molts its exoskeleton and grows a new one to cover its larger body."

    Yes and no. They have an exoskelleton to keep their limbs and bodies rigid like mamals have a skeleton, so it is like they have bones. However their exoskeletons are not made of the same stuff as our bones. The rigid parts of an insect aren't made of bone, but are made of Chitin, a polymer of sugars. Being a polymer makes it a lot like a form of natural plastic. The weight and flexibility of chitin over bone gives the spider some advantages.

    yes, spiders have an external cuticle-like skeleton called exoskeleton, meaning skeleton outside. It encloses the body cavity filled with blood. The blood and the cuticle-like skeleton are responsible for maintaining the spider's shape.

    spiders don't have bones, the shell serves as the body's skeleton. Because the skeleton is outside the body, it's called an exoskeleton ("exo-" means "outside.")

    No. Spiders have an exoskeleton with the musculature encased within.

    They have an exoskeleton, which means their "bones" are on the outside, pretty much.
