"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 known widely as dorado, it is one of two members of the Coryphaenidae family, the other being the pompano dolphinfish.
The name mahi-mahi means very strong in Hawaiian. In other languages the fish is known as dorade coryphène, lampuga, llampuga, lampuka, lampuki, rakingo, calitos, or maverikos." - Mr. Wkipedia
