Coryphaenidae

The Coryphaenidae are a family of marine ray-finned fishes belonging to the order Perciformes. The family contains only one genus, Coryphaena, which contains two species, both of which have compressed heads and single dorsal fins that run the entire length of the fish's bodies. Dolphinfishes are unrelated to dolphins (which are mammals) and their meat is often labeled mahi-mahi commercially to reduce possible public confusion. Dolphinfish are one of the fastest-growing species in the ocean and therefore serve as a primary food source for many pelagic predators.
