a backbone has a backbone and a no backbone doesnt but most of the backbone are full bone .e.g mamamls no backbone has no bones .e.g worm

well insects don't have backbones.they have exoskeletons thats. Cockroaches for example dont have back bones.Thats why when you squish them there is a crunch sound

It's a bone. In your back.Actualy, it is a bone that holds the central nervus system. A long strand of nerves that goes directly to your brain connecting to the other parts of your body.
