The yellowmouth grouper, also known as the crossband rockfish, grey mannock, hamlet, harlequin rockfish, princess rockfish, rockfish, salmon grouper, salmon rock fish or scamp, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the Caribbean and in the tropical waters of the Atlantic Ocean. It is also found in pockets in Brazil. It is a fairly large fish and it gets its name from the yellow around its mouth.
