Drums & croakers are notable for sounds produced by muscles attached to the swim bladder.  They feed upon fishes or invertebrates and are especially prolific over soft bottoms and estuaries.  They are an important component of the subsistence diet.  Common in warm seas & temperate around the world, none are present in Hawaii.
