Mahi
The mahi-mahi or common dolphinfish (Coryphaena hippurus) is a surface-dwelling ray-finned fish found in off-shore temperate, tropical, and subtropical waters worldwide. Also widely called dorado (not to be confused with Salminus brasiliensis, a freshwater fish) and dolphin, 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. The name mahi-mahi comes from the Hawaiian language and means 'very strong', through the process of reduplication. By chance in Persian, mahi (ماهی) means 'fish', but the word mahi-mahi is Hawaiian. Though the species is also referred to as the common dolphinfish, the use of dolphin can be misleading as they are not closely related to dolphins; see Coryphaena for the possible etymologies of dolphinfish. In parts of the Pacific and along the English-speaking coast of South Africa, the mahi-mahi is commonly referred to by its name in Spanish, dorado. On the Mediterranean island of Malta, the mahi-mahi is referred to as the lampuka. In Indonesian, they are called ikan lemadang.
