Sharks do not have bones, they have skeletons made of cartilage.
Sharks are cartilaginous fish. The term "cartilaginous fish" means that the structure of the animal's body is formed of cartilage, instead of bone. A shark does not have one bone in it's body. It's skeleton is made up of cartilage. Cartilage is a tough material, like the material that shaped your ear.
Since the shark has an entirely different body shape, it's hard to make a fair comparison. But if you'd pick to similarly sized bones, the shark's would be softer.
