All chordates embryos have pharngeal slits.
all chordates
At some point in all chordates' lives, they have a notochord, a nerve chord, gill slits and a tail. Some chordates are more complex though.
Chordates all possess a notochord (dorsal supporting rod), gill slits, and a dorsal nerve cord some time in their life cycles.
Gills I think, like pharyngeal gill slits ... maybe ....
all chordates have notochord, gill slits, postanal tail, and nerve chord.

Chordates are animals that comprise the vertebrates. The three structures that are present during their development are the notochord, a tubular nerve cord and gill slits leading into the pharynx.
