The Mahi Mahi is a slender pelagic species that occurs in tropical and warm temperate waters worldwide.
The Mahi Mahi has an elongate compressed body and a forked tail. Its long-based dorsal fin starts above or slightly behind the eyes.
The species is usually metallic blue-green above and silver with a golden sheen on the sides. There are iridescent blue to black spots on the sides.
The Mahi Mahi and Pompano Mahi Mahi can be separated by body depth (less than versus greater than 25% of standard length respectively). The tooth patch on the tongue is oval versus trapezoid. There are also differences in the number of dorsal fin rays, lateral line scales and vertebrae.
The species occurs in tropical and warm temperate waters worldwide.
In Australia it is known from marine waters around the entire country, but is more common in warmer waters.
