ACKNOWLEDGEMENTS 



The comprehensi\'eness of this book, by its nature, leaves us greatly in debt to 

 sexeral authors and publishers for their help and gracious cooperation in grant- 

 ing permission to reproduce drawings. The figures of plants, chapter 6, were 

 largely adapted from Marine Algae of the N orthwestern Coast of INorth America 

 by W. R. Taylor, University of Michigan Press and Marine Algae of the Mon- 

 terey Peninsula, California by G. M. Smith, Stanford University Press. The 

 drawings of sharks, chapter 8, were partly reproduced from Part I of Fishes 

 of the Western North Atlantic by H. B. Bigelow and W. C. Schroeder through 

 the courtesy of the Sears Foundation for Marine Research, Yale Uni\'ersity, 

 and from The Plagiostoma by Samuel Garman through the courtesy of 

 the Museum of Comparative Zoology, Harvard University. Many of the 

 drawings of fishes, chapter 9, were redrawn from The Fishes of North and 

 Middle America by D. S. Jordan and B. W. Evermann, a Bulletin of the 

 United States National Museum. The figures of turdes, chapter 10, were based 

 on illustrations from The Handbook of Turtles by Archie Carr, Comstock 

 Publishing Associates. Those of mamm.als were pardy based on illustrations 

 from The Field Book of North American Mammals by H. E. Anthony, 

 Putnam's Sons. 



All of the photographs except two by John A. Moore of Columbia University 

 were taken by the authors with the aid of Russell Kinne. It would not have 

 been possible to procure these photographs without the very kind cooperation 

 of Jim O'Doherty of Robinson-Hannagan Agency, New York, Don McCarthy 

 of the Bahamas Development Board, Nassau, and Abercrombie and Fitch Co., 

 New York, for the loan of the compressor shown in figure 15. 



We also wish to thank Peggy and Dennis Hickman of the Pilot Flouse club, 

 Nassau, and their surprised guests who were most understanding when they 

 discovered that we were using their swimming pool as a specimen tank. 

 Nora Wheatlv and Jean Wilmot were a great help in the typing of manuscript 

 and the correction of galleys. 



The text was improved through the advice of the following: animal behavior, 

 chapter 2, Dr. Helmut E. Adler and Dr. Evelyn Shaw, both of the American 

 Museum of Natural History in New York; photography, chapter 3, Peter Stack- 

 pole of Life Magazine; evolution, chapter 5, Dr. John A. Moore of Columbia 

 University; plants, chapter 6, Dr. F. G. Lier of Columbia University; reptiles,
