The Mahi Mahi or common dolphinfish (Coryphaena hippurus) is a surface-dwelling fish found in tropical waters worldwide. It is also sometimes called the Dorado and Dolphin, one of two members of the Coryphaenidae family, the other being the pompano dolphinfish.
A male Mahi Mahi has a large, blue dorsal fin and a prominent forehead similar in appearance to the Sperm Whale, but a female has a less prominent forehead taking more of a rounded shape. They are distinguished by dazzling colors – golden on the sides, and bright blues and greens on the sides and back. The pectoral fins of the mahi-mahi are iridescent blue. The flank is broad and golden. Out of the water, the fish often change color (giving reason to their Spanish name, Dorado, meaning “golden”), going through several hues before finally fading to a yellow-grey upon death.
Mahi-mahi are highly sought for sport fishing and commercial purposes. Sport fishermen seek them due to their beauty, size, food quality, and healthy population. Fishing charters most often look for floating debris and frigatebirds near the edge of the reef in about 120 feet (37 m) of water. Mahi-mahi (and many other fish) often swim near debris such as floating wood, five-gallon bucket lids, palm trees, and fronds, or Sargasso weed lines and around fish buoys.
