Crevalle jack
Alternative names: Caranx hippos
The Crevalle jack can be found in the tropical and temperate waters of the Atlantic Ocean, Pacific Ocean and Indian Ocean.
The Crevalle jack differs from other jacks by having a rounded black spot on the lower base of the pectoral fin and a vertically long black spot on the operculum.
Jacks are not highly valued as food, but they are of a big importance for gamefish because of their hard-fighting reputation. Also on the Internet you can find more articles on how to catch the Crevalle jack rather than the Crevalle itself so that says it all.
