Negaprion is a genus of requiem sharks, 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.

Species

Negaprion acutidens (Rüppell, 1837) (Sicklefin lemon shark)
Negaprion brevirostris (Poey, 1868) (Lemon shark)
