Overview

Found singly or in small schools close to coral and rocks over deep off-shore reefs.
Juveniles form schools.

Jacks are fast swimming fish that can roam over great distances. The larger fish hunt other fish and the smaller fish eat zooplankton. In turn they are hunted by large Tuna and Dolphins.
