Scientific name: Calamus nodosus
The knobbed porgy has a deep body with a very steep profile, and a nape that projects strikingly in adults. It exhibits a silvery or brassy body with a rosy cast and dark purplish cheeks and snout. A large blue blotch can be seen on its pectoral fin.
Knobbed porgies inhabit hard bottoms, coral reefs, and ledges.
These porgies can be found in south to eastern Florida.
