The classification of Vertebrates is comprised of mammals, birds, reptiles, amphibians,
rays and sharks, bony fish and cyclostomes (jawless fish like hagfish).
Vertebrates developed around 500 million years ago. Only the groups listed above fall into the category, all other animals (98%) are defined as invertebrates.
Simply stated, the characteristic that distinguishes the two groups is the presence or absence of a backbone or spinal cord, a brain case, and an internal skeleton. The vertebrates have an internal skeleton with a backbone and a central nervous system and invertebrates do not.
Another way to differentiate is that all vertebrates have obvious heads with eyes and other sensory organs at the front end of their bodies, unlike most invertebrates like worms, mollusks, jellyfish, starfish, coral, etc.
