The pompano dolphin (not related to the marine mammal) is a silvery, colourful fish with bright blue-green on top, yellow sides, and a white/gold underside. It has a long body, reaching up to 50 inches, with a distinctly forked caudal fin (tail) and a dorsal fin that runs the length of its body. Males grow bigger than females and develop a protruding forehead. They are smaller than their cousins, the common dolphinfish, but they’re still quite popular as a game fish.
