A member of the Carangidae family of jacks, the lookdown is so called because of its habit of hovering over the bottom in a partly forward-tilted position, which makes it seem to “look down.” The flesh of the lookdown has an excellent flavor and is commercially marketed fresh.
IdentificationBright silver and iridescent, the lookdown has a deep and extremely compressed body that may have goldish, greenish, bluish, or purplish highlights. One of its most striking features is the unusually high forehead, as well as the low placement of the mouth on the face and the high placement of the eyes.
The first rays of the second dorsal ﬁn and the anal ﬁn are long and streamerlike; in the dorsal fin, they may extend to the tail, whereas in the anal fin they do not extend as far. The lookdown may also have three or four pale bars across the lower body. On young fish, there are two very long, threadlike filaments that extend from the dorsal fin.
