Mangrove snapper are typically much smaller than cubera, but when they are of similar size, the two species can only be distinguished by examining the tooth patch on the inside roof of the mouth.

Many specimens caught in Florida, specifically Punta Gorda, are actually misidentified dogtooth or dog snapper, L. jocu.

The best way to distinguish between the two species is the dog snapper has a lighter triangle of color with a blue band under the eye and large, and sharp fangs in the front (canines), hence its common name.

The mangrove snapper feeds mostly on small fishes, crustaceans (such as crabs and shrimp), cephalopods, gastropods, polychaete worms and some planktonic items (including copepods and amphipods).
