The statements given below highlight some of the chordates features. They have a hollow nervous system which is present ventrally above the notochord. II. They prossess four pharyngeal gill slits present in the from of perfortions on the lateral sides of pharynx. III. Epidermis is made up of stratified epithelium. IV. They have two pairs of appendages, one pair at the begnning of the trunk and other in the middle of the trunk. V. They have a closed vascular system.
