Answer:
Sharks have cartilaginous skeletons, whereas salmon have bony skeletons.
Sharks and salmons are both vertebrates.
Explanation:
Fish are separated into two main types depending on what their skeleton is made of. Bony fish have skeletons made of bone, while cartilaginous fish have skeletons made of cartilage.
Sharks are classified as vertebrates, meaning they have a backbone. A shark's backbone is not really made out of bone it is cartilage. ... Sharks are grouped under the category of fish called cartilaginous fish. Other cartilaginous fish include rays and skates, which are similar to sharks.
