No, crab shells are not made of bone; they are composed of chitin, a tough, flexible polysaccharide, and are often reinforced with calcium carbonate. This material provides strength and protection to the crab's body. Unlike bones, which are part of the vertebrate skeletal system, crab shells are part of an exoskeleton that supports and encases the animal from the outside.
