Acanthocybium solandri (Cuvier)
(Wahoo; Tosun) (photo: 88.5 cm FL, Tarague)
FL: to 210 cm; IGFA all-tackle record: 67.6 kg (149 lb), Bahamas

In oceanic waters, Wahoo feed primarily on fishes, squids, and crustaceans.  In coastal waters they feed on young reef fishes as well as baitfish, flyingfish, and small tuna.  They are often found above deep dropoffs between 40 and 200 m.  Wahoo are among the fastest fishes, capable of reaching bursts of speed as high as 75 kph (47 mph).  Wahoo are caught throughout the year on Guam, although they are more abundant during November and December.
