JACK, Pacific crevalle / Caranx canines Glinther, 1869; CARANGIDAE FAMILY , also called torn, crevally, cavalla, jiguagua
This eastern Pacific species is identical in most respects to the crevalle jack (Caranx hippos) of the western Atlantic, including the characteristic black spot or blotch on the opereulum (gill cover) and on the pectoral fins. The Pacific species is distinguished externally only by the presence of a larger maximum number of scutes (up to 42, as opposed to 2635 in C. hippos). This and other differences documented by scientists have let to classification of the Pacific crevalle jack in recent years as a separate and valid species.
Behavior patterns, edibility and the general appearance of C. caninus are the same as for its western Atlantic counterpart.
