Notochord - ANSWER A rod of tough, flexible material that runs the length of a creature's body, providing the majority of its support and attachment sites for muscles. Is replaced by the backbone in vertebrates. pharyngeal gill slits - ANSWER Slits open to the outside from the pharynx. Function in filter feeding in invertebrates and are adapted as Eustachian tubes and middle ear bones in higher vertebrates. dorsal nerve cord - ANSWER A single nerve cord found in vertebrates. Invertebrates...
