fist off we are not shark's and shark's so not use internet. and for a matter of fact it's *shark's* because there is more then one shark in the oceans. and yes they do have back bones but Shark skeletons are very different from those of bony fish and land mammals. Sharks and other cartilaginous fish (skate and rays) have skeletons made of cartilage and connective tissue. Cartilage is flexible and durable, yet is about half the normal density of bone. This reduces the skeleton's weight, saving energy.Because sharks do not have rib cages, they can easily be crushed under their own weight on land.
