One unique feature is that the notochord and nerve cord, which are found along the entire length of the body, persist throughout life even in the adult phase. In some groups, some of these are present only during embryonic development. Notochord : flexible rod on the dorsal side of gut, present at one stage in all chordates; displaced in vertebrates by vertebral column that forms around the nerve cord. Adults are not free-swimming and attach themselves to a hard substrate and encase themselves in a tunic structure. A(n) ________ is an example of a chordate that is not a vertebrate. have a water vascular system that functions in locomotion feeding, and gas exchange, are the simplest bilaterian animals and lack a body cavity. B) They all exhibit radial symmetry. Chordates are animals who are vertebrates (having a backbone) or closely related invertebrates (lacking a backbone). Many scientists maintain that chordates originated sometime earlier than 590 million years ago; that is, they predate the fossil record.Such early representatives were soft-bodied and therefore left a poor fossil record. All of these characteristics are observed at some point in chordate development. Invertebrate chordates include tunicates and lancelets.
