Sering dikelirukan dengan: The blue stingray of southern Africa was once thought to be a variant of this species, but it is a separate species. The common stingray lacks the blue markings of the blue stingray. Tortonese's stingray of the Mediterranean is similar, and the difference between the two is poorly understood.1
