More typically, it has a length of 35 to 60 cm (14 to 24 in) and a weight of 0.4 to 2.5 kg (0.88 to 5.51 lb). The species can live as long as 25 years. They have compressed and elongated bodies, the upper portion is a bluish-silver colour, the belly is silver, and the sides are a yellow-silver shade. A small black blotch is found on the bony flap covering the gills. The fish have two dorsal fins, two small, detached spines in front of the rear fin, and a deeply forked tail fin. Between two and four years of age, the silver trevally becomes sexually mature and is able to reproduce.
