Surgeonfishes of the World (Bishop Museum Bulletin in Zoology)
No one is better qualified to write this book.  John E. Randall's PhD thesis was on the classification of the Acanthuridae and the biology of the Hawaiian subspecies of the Convict Surgeonfish.  As one of the pioneers of a new generation of scuba-diving biologists, he has contributed more towards the classification and identification of coral reef fishes than anyone during the past century.  He has published nearly 600 scientific papers and semipopular articles on marine biology, mainly on tropical marine fishes, as well as guidebooks on the fishes of Hawaii, the Caribbean Sea, Red Sea, Maldive Islands, Great Barrier Reef and Oman.
