Do great white sharks have backbones?

Answer 1

yes they do

Answer 2

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.

Answer 3

Yes. All fish are vertebrates and they have backbones. A shark's skeleton is different because it is cartilage instead of bone, but sharks do have spines.
No sharks do not have a backbone. Backbones are made up of, well, bone; sharks have no bones they have cartilage instead. Their "backbone" is made up of cartilage.

Answer 4

No, sharks are 100% cartilage.

Answer 5

Angle Fish have backbones.
