Blacktip sharks from these two regions differ in morphology, coloration, and life history characteristics, and the eastern Atlantic lineage may merit species status. [8] Fossil teeth belonging to this species have been found in Early Miocene (23–16 Ma) deposits in Delaware and Florida. [9] [10]
It can be distinguished from similar species by its teeth, which are narrow, erect, and smooth-edged. Little is known of the smoothtooth blacktip shark's natural history; it likely inhabits shallow waters and feeds on small bony fishes. It is presumably viviparous like other members of its family.

Its common name comes from a characteristic black blotch on the tip of its snout, though this may be indistinct in older individuals.
