Spiders do not have a backbone because they belong to a group of animals called arachnids, which have an exoskeleton instead of an internal skeleton. This exoskeleton provides support and protection for their bodies. Spiders are able to move and function effectively without a backbone due to this exoskeleton.
Insects, spiders, crustaceans, and anything with an exoskeleton.
