The primary difference between the two is that vertebrates possess a backbone and an internal skeleton. Chordata also contains two clades of invertebrates: Urochordata and Cephalochordata. Invertebrates use a nonadaptive, innate immunity, the expression of germline encoded receptors, to identify the allogeneic and xenogeneic attributes. This fluid-filled cavity (coelom), located between the body wall and digestive tract, is what differentiates coelomates from acoelomates. A nerve cord is enclosed by vertebrae — individual bones that make up a vertebrate's spine. Invertebrates.
