Wahoo

The wahoo is a scombrid fish found worldwide in tropical and subtropical seas. In Hawaii, the wahoo is known as ono. The species is sometimes called hoo in the United States. It is best known to sports, as its speed and high-quality makes it a prized and valued game fish. Its body is elongated and the back is an iridescent blue, while the sides are silvery with a pattern of irregular vertical blue bars. These colors fade rapidly at death. The mouth is large, and the teeth of the wahoo are razor sharp. Both the upper and lower jaws have a somewhat sharper appearance than those of king or Spanish mackerel. Specimens have been recorded at up to 2.5 metres (8 ft 2 in) in length, and weighing up to 83 kilograms (183 lb). The growth of the fish can be quite quick.
