Chordates all have:
A bilateral body plan.
Notochord, (stiff rod of cartilage that extends along the inside of the body) Sometimes would develop into a spinal chord
A dorsal neural tube. (Spinal cord)
Pharyngeal slits.
Post-anal tail. A muscular tail that extends backwards behind the anus.
An endostyle. This is a groove in the ventral wall of the pharynx. In filter-feeding species it produces mucus to gather food particles.
