Question No.  7001 :
Do sharks have backbones?

Sharks are vertebrates. They do have a vertebral column, giving them support and protecting their central nervous system. However, they are not bony fishes (or Osteichthyes). They are cartilaginous fishes (or Chondrichthyes). Their skeleton is entirely made of a tough, elastic substance called cartilage.
