The Mangrove red snapper (commonly called mangrove jack within Australia), Lutjanus argentimaculatus is a species of snapper. It is also known as creek red bream, the Stuart evader, dog bream, mangrove red snapper, purple sea perch, purple sea-perch, red bass, red bream, red perch, red reef bream, river roman or rock barramundi.
Coloration of the mangrove red snapper ranges from burnt orange, to copper, to bronze and dark reddish-brown, depending on its age and environment. Younger fish caught in estuarine areas are often darker than older fish taken from offshore reef areas, and exhibit lighter vertical bands down their flanks. In reef areas, mangrove red snappers are sometimes confused with two-spot red snapper or red bass (Lutjanus bohar), a known carrier of ciguatera toxin. The red bass, however, is usually darker in coloration, has fewer dorsal-fin spines, scale rows on the back that rise obliquely from the lateral line, and a deep groove from the nostrils to the eyes. Mangrove red snapper is a popular and important commercial and recreational fish throughout its range, and considered to be an excellent food fish. The mangrove red snapper is a highly regarded table fish with firm, sweet-tasting, white flesh.
