Definition of cephalochordate

: an animal of the subphylum Cephalochordata : lancelet Although cephalochordates had achieved the primary characters of chordates—notochord, dorsal hollow nerve cord, and pharyngeal gill slits—as well as a postanal tail and segmental muscles throughout the trunk and tail, they lack many other features that characterize vertebrates.— Robert L. Carroll, Patterns and Processes of Vertebrate Evolution, 1997
