Open SlotGauge for DolphinSpecies of fish
The mahi-mahi, common dolphinfish, dolphinfish, dolphin or dorado is a surface-dwelling ray-finned fish found in off-shore temperate, tropical, and subtropical waters worldwide. It is one of two members of the family Coryphaenidae, the other being the pompano dolphinfish. These fish are most commonly found in the waters around the Gulf of Mexico, Costa Rica, Hawaii, and the Indian Ocean. In Italy it is called corifena, lampuga or pesce capone, and has even given its name to the caponata though eggplant has now taken the place of the fish.
