gnathostomata
/ˌnæθoʊstəˈmɑːtə/Jawed vertebrates, including fishes and tetrapods
From Greek gnatho- (jaw).
Word Ancestry
Picture a fish with a hinged mouth snapping shut: that bit of anatomy is exactly what this formidable name puts on stage. Greek gnáthos meant “jaw,” while stóma meant “mouth,” so Gnathostomata is essentially the scientific equivalent of “the jaw-mouth ones.” The name was designed for a biological revolution: unlike jawless vertebrates such as lampreys, these animals possess articulated jaws derived from the skeletons of ancient gill arches. Their descendants now include everything from sharks and salmon to lizards, birds, and humans—roughly 99 percent of living vertebrate species. The mouth in stóma also appears in familiar terms such as stomatology, the study of the mouth, making Gnathostomata easier to remember: gnatho tells you what bites, and stoma tells you where it bites.
