Wahoo is a Great catch.
Wahoo’s elongated body has small, barely visible scales. Its back shimmers iridescent blue, while the sides appear silvery with irregular vertical blue bars and razor-sharp teeth. These colors quickly fade after death. The fish boasts a large mouth, and both upper and lower jaws are sharper than a king or Spanish mackerel.
Specimens have been recorded at up to 2.5 m (8 ft 2 in) in length, and weighing up to 83 kg (183 lb). Growth can be rapid. One specimen tagged at 5 kg (11 lb) grew to 15 kg (33 lb) in one year. Wahoo can swim up to 60 mph (97 km/h). They are some of the fastest fish in the sea.
The wahoo may be distinguished from the related Atlantic king mackerel and from the Indo-Pacific narrow-barred Spanish mackerel by a fold of skin that covers the mandible when its mouth is closed. In contrast, the mandible of the king mackerel is always visible as is also the case for the smaller Spanish mackerel and Cero mackerel. The teeth of the wahoo are similar to those of king mackerel, but shorter and more closely set together.
The barracuda is sometimes confused with mackerel and wahoo but is easily distinguished from the latter two species. Barracuda have prominent scales, larger, dagger-like teeth, and lack the caudal keels and blade-like (forked) tail characteristic of the scombrid (mackerel)
