What do sharks have instead of a bone?
Asked in Great White Sharks
Do great white sharks have backbones?
Yes. All fish are vertebrates and they have backbones. A shark's skeleton is different because it is cartilage instead of bone, but sharks do have spines. No sharks do not have a backbone. Backbones are made up of, well, bone; sharks have no bones they have cartilage instead. Their "backbone" is made up of cartilage.
