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.

Yes, jawless fish have skeletons, but their skeletons are not made up of bone. Instead, their skeletons are cartilaginous, meaning their skeletons are made up of cartilage.

Most "regular" fish, such as the angelfish, have a skeleton made of bone (class osteichthyes, I think). Fish such as sharks, skates, and rays have a skeleton made of cartilage (class chondrichthyes). Even bony fish, though, such as your angelfish, have some cartilage for flexibility. I believe that the baby bony fish, like a human fetus, has pure cartilage until the bone forms. DL
