= notochord = Lengja sem styður við beinagrind með einskonar vökvaþrýstingi
= Holur, kviðlægur taugastrengur = dorsal, hollow nervechord
= Pharyngeal Gill Slits
= post anal tail
= Möttuldýr
Einkenni:
= Tálknmunni
Einkenni:
Munur á tálknmunna og hryggdýrum
= Vertebrate cephalization
= Vertebrate segmentation
= Vertebrate coelom
= Vertebrate circulatory system
= Vertebrate endoskeleton Innri stoðgrind Vel þroskuð Bein og/eða brjósk Kúpa umlykur heila Hryggsúla úr hryggjarliðum
= Vertebrate appendages
= Vertebrate genital and excretory systems
Tengsl seildýra Möttuldýr og Tálknmunnar = nánustu ættingjar hryggdýra Nýjar vísbendingar í sameindalíffræði sýna að: möttuldýr eru systurhópur hryggdýra Tálknmunnar eru skyldari skrápdýrum
Uppruni hryggdýra Steingervingur af fornu seildýri, Pikaia, fannst í Burgess Shale í Yoho Natinal Park
