 Juveniles are known to inhabit either inshore habitats such as estuaries, with an influx of these small fish after spawning in South Africa, while in other cases juveniles have been found living pelagically around floating objects.There has been one documented hybrid involving the bigeye trevally, a cross between "C. sexfasciatus" and "C. melampygus" (bluefin trevally), taken from the waters of Kane'ohe Bay, Hawaii.The specimen was initially thought to be a bigeye trevally, however a lack of the black opercular spot, light coloured scutes and a smaller than normal eye led to the specimen being examined in more detail.
