Bullet mackerel is a small fast fish from the mackerel family. It lives in the open sea of warm oceans and hunts small animals.
Bullet mackerel differs from related tunas by small scales near the pectoral fins and special dark stripes on the back. It serves as an important link in the marine food chain and food for large predators.
Immature form that undergoes metamorphosis before adulthood.
