What Divers Should Know About Wahoo

Catching a fleeting glimpse of an iridescent blue flash often signals the presence of a wahoo. Its elongated body, distinctively marked with silvery sides and irregular vertical blue bars, helps it stand out in tropical and subtropical seas worldwide. Renowned for its speed, this impressive scombrid also possesses a large mouth equipped with razor-sharp teeth, giving its jaws a noticeably sharper appearance than many other mackerel species.

These powerful fish can reach substantial sizes, with specimens recorded up to 2.77 meters (9 ft 1 in) in length and weighing over 83 kilograms (183 lb). Occupying oceans from the Atlantic to the Indo-Pacific, wahoo are circumtropical in distribution, feeding primarily on other fish and cephalopods like squid. Females are often more numerous than males in their populations, a common trait among many pelagic marine species.
