The animal on the cover of Efficient Android Threading is mahi-mahi, or the common dolphinfish (Coryphaena hippurus). This ray-finned fish is a surface-dweller that is found in temperate, tropical, and subtropical waters. The name mahi-mahi translates to “very strong” in Hawaiian. Despite its alternate name of “dolphinfish,” mahi-mahi are not related to the marine mammals. There are two species of dolphinfish: the common dolphinfish and the pompano dolphin. Along the English speaking coast of South Africa, these fish are often called by the Spanish name, Dorado.

Mahi-mahi can grow up to 15–29 lb, seldom exceeding 33 lb. They can live up to five years, but average around four years. The mahi-mahi’s compressed bodies have long dorsal fins that extend almost the entire body length. Mahi-mahi are characterized by their brilliant colors: broad golden flank with bright blues and greens on the side and back, and three diagonal black stripes on each side of the fish. These colors change after the fish is caught; out of water, mahi-mahi cycle through several colors before fading to a yellow-grey when it dies.

Males and females are distinguished by their head shapes: males have prominent foreheads that stick out past the body, whereas females have rounded heads. Within the first year, both males and females are sexually mature, around 4–5 months. Females can spawn two to three times a year, producing 80,000–1,000,000 eggs per spawn.

Mahi-mahi is primarily consumed in the US and Caribbean ...
