Bar Jack

A slim, silvery jack marked by a dark stripe along the back that intensifies to near-black when the fish is excited or hunting, often seen shadowing stingrays and eagle rays to snatch small prey the larger animal disturbs from the sand. Also patrols cleaning stations, taking advantage of parasite-removal services from cleaner fish and shrimp.

Reef edges, sand flats and open water
