. "Negaprion is a genus of requiem sharks in the family Carcharhinidae, containing 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."@en . . . . . .
