JAWLESS

jawless: translation

fishes lacking jaws are vastly outnumbered by jawed fishes. The living Agnatha, hagfishes and lampreys, number about 108 species. This is a paraphyletic group and, as well as lacking jaws in contrast to the jawed fishes, also lacks pectoral and pelvic fins, has one or two semicircular canals, no scales, no bones, no vertebral centra but only a notochord, and pores rather than slits as gill openings
