The Wahoo is characterized by its very elongated, tuna-like body, blue-green on the top and silver on the sides, with a very short snout, a massive set of teeth, and a very elongated continuous dorsal fin. The Wahoo also has 24 to 30 distinguishing blue bars, some of which are double Y-shaped, on its sides. There are 8 to 9 finlets between the dorsal fin and the caudal fin and 9 finlets between the anal fin and the caudal fin.
The Wahoo, known for its horrific long runs, is not easily confused with other species, but smaller versions are similar in size and shape with the Gulf Sierra, Scomberomorus concolor (no extended dorsal, and spots on the sides not stripes) and the Pacific Sierra.
The Wahoo is one of the most prized of gamefish found in Mexican waters.
The world record, as of 2004, was caught in the Loreto area and weighed in at 158 pounds 8 ounces. This species is most commonly caught trolling on lines fortified with strong wire leaders.
