The "true" tunas are those that belong to the genus ''Thunnus''. Until recently, it was thought that there were seven ''Thunnus'' species, and that [[Atlantic bluefin tuna]] and [[Pacific bluefin tuna]] were [[subspecies]] of a single species. In 1999, Collette established that based on both molecular and morphological considerations, they are in fact distinct species.<ref>{{cite conference |last=Collette |first=B.B. |conference=5th Indo-Pacific Fish Conference: Nouméa, New Caledonia, 3–8 November 1997 |editor=Séret, B. |editor2=Sire, J.Y. |title=Mackerels, molecules, and morphology|year=1999|publisher=Société Française d'Ichtyologie [u.a.] |book-title=Proceedings |location=Paris |isbn=978-2-9507330-5-4 |pages=149–164 |url=https://oceanrep.geomar.de/id/eprint/5305/1/010021303.pdf }}</ref><ref name=Tanaka2006>{{cite journal |last1=Tanaka |first1=Y. |first2=K. |last2=Satoh |first3=M. |last3=Iwahashi |first4=H. |last4=Yamada |title=Growth-dependent recruitment of Pacific bluefin tuna ''Thunnus orientalis'' in the northwestern Pacific Ocean |journal=Marine Ecology Progress Series |year=2006 |volume=319 |pages=225–235 |id={{INIST|18108521}} |doi=10.3354/meps319225 |bibcode=2006MEPS..319..225T |doi-access=free}}</ref>

The genus ''Thunnus'' is further classified into two [[subgenera]]: ''Thunnus ([[Thunnus (subgenus)|Thunnus]])'' (the bluefin group), and ''Thunnus ([[Neothunnus (subgenus)|Neothunnus]])'' (the yellowfin group).<ref>{{cite book |doi=10.1016/B978-0-12-809633-8.20540-2 |chapter=Migration and Navigation in Fish |title=Encyclopedia of Reproduction |date=2018 |last1=Ueda |first1=Hiroshi |pages=84–89 |isbn=978-0-12-815145-7 }}</ref>
