Negaprion is a genus of requiem sharks in the family Carcharhinidae.{{cite WoRMS |author= Froese, R. and D. Pauly|year=2018 |title=Negaprion Whitley, 1940 |id=105721 |access-date=5 August 2018}} It contains the two extant species of lemon sharks: the lemon shark (N. brevirostris) of the Americas, and the sicklefin lemon shark (N. acutidens) of the Indo-Pacific. Both species are large, slow-moving, bulky sharks inhabiting shallow coastal waters, and can be identified by their short, blunt snouts, two dorsal fins of nearly equal size, and uniform yellowish brown or gray coloration.
