The false killer whale has been known to interact non-aggressively with several dolphin species: the common bottlenose dolphin, the Pacific white-sided dolphin ("Lagenorhynchus obliquidens"), the rough-toothed dolphin ("Steno bredanensis"), the pilot whales, the melon-headed whale, the pantropical spotted dolphin ("Stenella attenuata"), the pygmy killer whale, and Risso's dolphin.
