backboned
Possessing a spine
Backboned means having a backbone or spinal column—the defining feature of vertebrates.
The word appears most often in biological contexts: backboned animals as opposed to invertebrates.
Figuratively, it can describe someone with resolve or moral strength, though "spineless" is far more common than "backboned" for describing character.
