"Horse-eye Jack," Wikipedia, the free encyclopedia. The horse-eye jack is a gamefish and minor commercial fish in the family Carangidae. It is also known as the big-eye jack, and is similar in appearance to the crevalle jack, although the head of the horse-eye jack is not as blunt. The horse-eye jack is known to feed on smaller fish and on many invertebrates, such as shrimp and crab.The horse-eye jack is commonly found in the subtropical Atlantic ocean from Bermuda and the northern Gulf of Mexico and south to Rio de Janeiro. In the eastern Atlantic, it is found from St. Paul's Rocks to Ascension Island and, rarely, the in the Gulf of Guinea. It is a pelagic fish. It can be found on reefs and offshore oil rigs. The juvenile can be found closer to shore along sandy and muddy bottoms. The species may venture into brackish waters and can live in river mouths, but it is typically found in saltwater up to 140 m in depth. The adult horse-eye jack commonly swims with others in a school, either as one species or mixed with crevalle jack. Sometimes it also swims as a pair with a member of a very different species, such as Halichoeres radiatus, a type of wrasse.
