First sentence: The success of the chordates resulted in part from the presence of the following diagnostic morphological features that are present at some time during the life cycle: (1) a dorsal, hollow nerve cord that forms embryonically as a tube; (2) a notochord as the axial body support; (3) pharyngeal pouches or clefts (forming gill slits in fishes and larval amphibians); (4) an endostyle; and (5) muscular postanal tail.
