The four most prominent characteristics that distinguish chordates from species in all other phyla are the presence of a post-anal tail, a notochord, a dorsal, hollow nerve cord, and pharyngeal slits (also called gill slits)..
Then, what do hagfish and lampreys have in common with extinct conodonts?
skeletal rods that had supported pharyngeal (gill) slits.
Additionally, which is not a shared characteristic of all chordates? A ventral, solid cord is not a shared characteristic of all chordates. Instead, chordates are characterized to have a notochord, a dorsal hollow nerve cord, pharyngeal slits and a post-anal tail.
