A specimen of Cottonmouth jack Uraspis secunda (Poey, 1860) was recorded for the first time from the coast of Senegal. The specimen was immature measuring 118 mm for total length and 19.2 g for total body weight. In this note, the authors present a short description of one specimen and its main morphometric measurements and meristic characters. The distribution of U. secunda in its new area of capture is commented and discussed, together with its close relative species U. helvola (Forster, 1801).
