What is the NatureServe global conservation rank assigned to *Thunnus obesus*?
Answer
G4 (Apparently Secure)
The taxonomic assignment of *Thunnus obesus* directly impacts its perceived conservation status, which is assessed by organizations like NatureServe. This organization assigns a global rank based on the accepted scientific identification of the species. For Bigeye Tuna, this assigned rank is G4, signifying that the species is considered Apparently Secure globally. This designation is predicated on the scientific consensus regarding what *T. obesus* entails; if genetic studies were to successfully split this species into multiple distinct populations, the conservation status of those newly defined groups would require independent re-evaluation.
