It doesnt have Vetebral Columb {Notochord}
But it might have exoskeleton (Eg shells, thick skins etc) which acts as vetebral columb for them.

Time trip! I flashed back to arguing with one of my grade school teachers (Mr. Dan Wheeler) who had insisted that turtles were invertebrates because their backbones were attached to their shells rather than *inside* their bodies. It did wonders for any inclination to automatically accept spewage from authority figures.
Invertebrates do not have a jointed backbone or spine. If a person has an operation to fuse his or her spine, it does *not* make him or her an invertebrate. It doesn't need to actually be bone. I can be cartilage (i.e. sharks).

A backbone.
Invertebrate is a term coined by Chevalier de Lamarck to describe any animal without a backbone or vertebra, like insects, squids and worms.
