Some of them do.
Although the majority of animals that make up the phylum Chordata are vertebrates, some invertebrates are also part of this phylum. All animals which have a spine, or backbone, are classified in the phylum Chordata. There are three subphylums in Chordata: Urochordata (tunicates e.g. marine filter feeders such as sea squirts), Cephalachordata (lancelets e.g. sessile burrowing marine animals), and Vertebrata (vertebrates - mammals, birds, fish, reptiles and amphibians).
This phylum includes all animals which have a hollow nerve cord and a notochord at some stage during their development. In the case of vertebrates, the notochord is present in the embryo, and develops into the vertebral body.
