Revised in both format and content, this new edition of the standard "Fishes of the Gulf of Mexico "is based on two decades' research and greater attention to deepwater habitats. The authors have revamped the taxonomic nomenclature for more than forty species and included new photos and information obtained from dives around reefs and new offshore oil structures. Other habitat conditions have changed because of severe freezes, hurricanes, intensive fishing, and government regulations on fishing. The continued accumulation of data from sport anglers and commercial fisheries is also reflected in this new volume.
