Wahoo is a dark blue fish. The body is elongate and covered with small, scarcely visible, scales; the back is an iridescent blue green, while the sides are silvery, with a pattern of vertical blue bars. These colors fade rapidly at death. The mouth is large, and 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 8 ft in length, and weighing up to 180 lb. Growth can be rapid. One specimen tagged at 11 pounds grew to 33 pounds in one year. Wahoo can swim up to 47 miles per hour.

The flesh of the wahoo is delicate and white and regarded as very good in quality. This has created some demand for the wahoo as a premium priced commercial food fish. However, because of its solitary lifestyle, it is taken commercially only as a bycatch in the long-line fishery for Tuna and Dolphin. Wherever found, it is a prized sport fishing catch. Not always catchable, but otherwise it can be very delicious.

Wahoo meat has Large circle flakes, and a sweet firm texture.
