The mahi-mahi, meaning very strong in Hawaiian, are also known as dolphinfish. They are a surface-dwelling ray-finned fish found in off-shore waters worldwide. They are also known as Dorado, which means golden in Spanish for their lit up color.   Their sides are golden yellow with bright blues and greens on the sides and back.  Mature males, also called bulls, have prominent, bulging foreheads.  Females have a rounded head. Females are also usually smaller than males.  Mahi-mahi can live up to 5 years and weigh an average 15 to 29 lbs.  Big male bulls can weigh as much as 30 to 40 lbs.

Mahi-mahi are among the fastest-growing fish. They spawn in warm ocean currents throughout much of the year, and their young are commonly found in seaweed. Mahi-mahi are carnivorous, feeding mainly on flying fish, crabs, squid, and mackerel.
