Wahoo have silvery colored scales with a dark, blue-green colored back. Its sides, or flanks, have light blue stripes or barring. People often mistake this species for a barracuda for this reason. Adults typically reach about five or six feet long, but exceptionally large individuals can surpass eight feet in length. People in Hawaii call this species of fish "ono." The word roughly translates to "good to eat." and Ironically enough, the common name of this species also came from the Hawaiian Islands. When Europeans first encountered the islands of Hawaii, they often misspelled Oahu as "Wahoo." This misunderstanding led to the European term for this species.
