The garfish is a long and slender fish with a laterally compressed body, and grows to about in length. The jaws are elongated and armed with sharp teeth. The pectoral, dorsal, and anal fins are situated well back on the body and the latter two are similar in appearance. Positioning the fins so far back gives greater flexibility to the body. The
lateral line is set low on the flanks. The colour of the body is bluish green with a silvery grey belly and the bones are green. Garfish are
pelagic fish which live close to the water surface. They eat small fish and have a migratory pattern similar to that of the
mackerel, arriving a short time before the latter to spawn. Their association with mackerel has led to some older common names such as "mackerel guide" and "mackerel guardian". ==Behaviour==
