Remarks: Stenella attenuata was initially included in S. frontalis and regarded as a distinct species. Two subspecies of Pantropical spotted dolphin were recognized by mtDNA analysis (Escorza-Trevino et al. 2005): S. a. attenuata in tropical oceanic waters worldwide, and S. a. graffmani in the coastal waters of the eastern tropical Pacific Ocean (Perrin 2002). Stenella a. attenuata (Gray, 1846) inhabits the waters of Korea.
