This group includes a large group of vertebrates. Some examples of chordates are sharks and frogs. All chordata have at some point these four attributes. Pharyngeal slits are slits in the neck and are often used as gills. A dorsal nerve cord is a group of nerve fibers along the back. A notochord which is rod running underneath and supports the spine. Finally the post anal tail which is an extension of the body past the anal opening.
