How many bones are in a shark's body?
Sharks are a type of fish that have no bones, only cartilage. Some parts of their skeleton, like their vertebrae, are calcified. Cartilage, a strong fibrous substance, is softer than bone; our nose and ears are made of cartilage. Sharks belong to the group of fishes called Elasmobranchii, which also includes the rays, skates, and ratfish. The Elasmobranchii are all fish that have no bones, only cartilage.

What are called elasmobranch?
Elasmobranch is a class of fishes with bones made of cartilage. It includes sharks, skates and rays. Cartilage is the material that is in your nose and ears. Their only real bones are teeth and jaws. They are a very old, successful class of fishes. There were sharks before there were dinosaurs. Because they lack bones, there are very few fossils of older sharks. Sharks are endangered now because their cartilaginous fins are prized for soup in some cultures.

Do sharks and rays have bones explain?
Sharks and rays belong to a class of animals known as Chondrichthyes (say it : Con - Dree- Ek - theees) which are known as the cartilaginous fishes.These animals DO have bones, but not bone tissue like ours, their bones are made out of cartilage and do not contain bone marrow like us, so their red blood cells are produced in their spleens. Their teeth which are harder than their caritlage bones are made out of calcified tissue called dentine and hard enamel which would more closely resemble the structure of human teeth but they are not bones in the sense that they are calcified tissue which is a support structure for our bodies.Other animals in this class which are not sharks or rays are the Chimaeras, which look like a mixture of a shark and a ray, and are also known as Ghostfish, and the Skates which are another weir looking animal which resemble neither a shark or a sting ray.
