I have a vast reference Library to suit my varied hobbies one of which is underwater photography specifically of, yes you guessed it- coral reefs!
I like to identify and name my photographs, a little foible of mine so part of the fun is when I return home and start my research. That is where my physical Library comes in, nothing like keeping it old school for me.
This is my go to first book, it covers fish, reptiles, mammals, invertebrates and marine plants and whilst no publication can feature everything, it tries and therefore it is a hefty book.
Beautiful clear photographs accompany the descriptions, assisting you in identifying what you have seen on your dives. Sections on Geology, Conservation, Dive sites, Dangerous Marine Life to watch out for and so much more.
Cannot fault this book in short.
