✌Most vertebrates possess guts with a non-terminal anus.
✌The mouth cavity and the oesophagus is connected by the pharyngeal gill slits to a muscular tube pharynx, which opens to the exterior.
✌They possess a dorsal hollow nerve tube at some stage of their life.
✌Possess a dorsal cartilaginous nerve rod known as the notochord.
✌At some stage of their life possess gill slits in the pharyngeal region.
✌Have partially open circulatory system.
✌Possess two pairs of appendages.
✌The endoskeleton is made of cartilage or bone.
✌The first vertebrates were jawless fishes with single caudal fin.
✌The advancement of vertebrates with a hinged jaw which opened new food options and jawed fishes became the dominant creatures in the sea.
