Cephalopods of the Broad Caribbean: Distribution, Abundance, and Ecological Importance
The Broad Caribbean region is defined as the Gulf of Mexico, and the coastal and marine areas of the Caribbean Sea, including the chain of islands forming the Greater and Lesser Antilles, Turks and Caicos, the Bahamas, and the gulf coasts of the United States, Central and South America (Stanley, 199...
