+Chordates are a phylum of [Animals](/wiki/animals) defined by a shared body plan, which at some developmental stage includes a [Notochord](/wiki/notochord), dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. This incredibly diverse group encompasses all [Vertebrates](/wiki/vertebrates), from fish to humans, as well as simpler marine creatures.
