Sharks are vertebrates (they belong to the phylum Cordata), so they have a spinal chord. However they are also cartilaginous fishes (they belong the the class Chondrichthyes) meaning that their skeleton is made of cartilage instead of bone. They do have a cartilage sheath that surrounds their spinal chord which could be considered a spine. There could be a semantic debate over whether that constitutes a spine, but I for one think it does.
