Taxonomy and systematics
The genus Balaenoptera contains the following extant species and subspecies:[2][5]
- Common minke whale (Balaenoptera acutorostrata)

- Sei whale (Balaenoptera borealis)
- Northern sei whale(Balaenoptera borealis borealis)
- Southern sei whale(Balaenoptera borealis schlegelii)
- Bryde's whale (Balaenoptera edeni)
- Offshore Bryde's whale (Balaenoptera brydei or Balaenoptera edeni brydei) (taxonomy disputed)[6][7]
- Eden's whale(Balaenoptera edeni edeni)
- Blue whale (Balaenoptera musculus)
- Northern blue whale (Balaenoptera musculus musculus)
- Antarctic blue whale (Balaenoptera musculus intermedia)
- Northern Indian Ocean blue whale (Balaenoptera musculus indica)

- Southern fin whale (Balaenoptera physalus quoyi)
- North Pacific fin whale (Balaenoptera physalus velifera)

Fossil species
Many fossil Balaenoptera species have been described. Some (namely B. borealina, B. definata, B. emarginata, B. gibbosa, B. rostratella, and B. sibbaldina) are either nondiagnostic, highly fragmentary, or had no
The valid fossil species of Balaenoptera are:- †
- †Balaenoptera cephalus was originally thought to be a species of Eschrichtius (gray whales) or Cetotherium, but more recent analysis shows it to be a member of Balaenoptera.[11] Fossils of the species were found in the Calvert Formation of Maryland.[12]
- †Megaptera novaeangliae (the humpback whale), B. siberi, and B. physalus (the fin whale).[13]
- †"Balaenoptera" cortesii is a small species based on a juvenile specimen from Montezago; it probably represents a distinct, unnamed genus of balaenopterid.[8]
- †dentary.[15]
- †"Balaenoptera" portisi is based on MGPT 13803 from Cetotheriophanes capellinii. The species "B. floridana" is indistinguishable from "B." portisi.[8]
- †"Balaenoptera" ryani is a valid species but is not in fact a species of Balaenoptera. It probably represents a distinct genus of basal balaenopterid.[8]
- †Balaenoptera siberi is known from two complete skeletons. Its affinity with the genus Balaenoptera has been questioned.[8][16]
- †tympanic bone.[17]
