The pompano dolphinfish (Coryphaena equiselis) is a species of surface-dwelling ray-finned fish found in tropical and subtropical waters. They are one of only two members of the family Coryphaenidae, the other being the mahi-mahi or common dolphinfish.
Pompano dolphinfish have a lifespan of three to four years. They are often mistaken for juvenile mahi-mahi; they are somewhat smaller than the related mahi-mahi, only reaching a maximum total length of 127 cm (50 in). Pompano dolphinfish have compressed heads and dorsal fins extending the entire length of their bodies. Their backs are a brilliant blue-green, and their sides are a silvery-golden color. Mature males develop a protruding forehead, but not to the same extent as male mahi-mahi. When they are removed from the water, the fish fade to a muted green-grey upon death.
