Chilean jack mackerel for Pacific jack mackerel. The Chilean jack mackerel looks very much like the greenback horse mackerel "(Trachurus declivis)" found around Australia and New Zealand. The two species can be distinguished by the number of gill rakers ("T. declivis" 50–57, "T. murphyi" 51–65) and the number of scales and scutes in the lateral line ("T. declivis" 81–82, "T. murphyi" 89–113).
