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.
