since my pictures from Coz went up I've been trying to ID some of the fish and other marine life that I took pictures of, sometimes successfully, other times shamefully unsuccessfully. However, while we were in Curacao, they had a great book there to help ID the local marine life, which I was able to find at Amazon.ca called "REEF FISH IDENTIFICATION - Florida, Caribbean Bahamas" by Paul Humann and Ned Deloach. For anyone looking for a good reference to ID the fish and coral that they've seen, this book is one of the best I've seen. Amazon also had it's companion book "REEF CREATURES IDENTIFICATION - Florida, Caribbean and Bahamas" by the same authors as a special deal, it came to about $60 with taxes, and no shipping. Great deal if you need this kind of resource.
Here is a link to amazon with the package. I'll be updating my pics with some names of the fish and coral shortly as I go through this book. :D
