Query: Not A Lot of Information

I was pretty disappointed in this book, as its Amazon reviews suggested it was the subject's definitive resource. I found the book's section on crocodilians (my main interest) to be lacking. Unfortunately, the book was the most expensive of any, on crocodilians I've purchased, and provided probably the least information. The author's source of information on crocodilians appears to have been limited to specimens kept in zoos, and even that was not based on first-hand experience. The author's description of crocodilians is general, at best, and in some instances erroneous. For a better buy, pick up a copy of Charles Ross' (Editor) "Crocodiles and Alligators", or Lynne Kelley's "Crocodile" if you're interested in the history of crocodilians in life and mythology.
