[29] In these estuaries, the giant trevally is known from both highly turbid, dirty water to clean, high visibility waters, but in most cases, the species prefers the turbid waters. [36] Research has been conducted on the movements of larger fish around their habitats, as well as the movement between habitats as the species grows, to understand how marine reserves impact on the species. [22] Juveniles and subadults commonly school, both in marine and estuarine environments. [14] Traces of broad cross-bands on the fish's sides are occasionally seen after death. This later revision in classification saw the species moved to the genus Caranx, where it has remained. Eggs are described as pelagic and transparent in nature.
