You may get some funny looks as you stick your head into this book to look through the 3-D glasses, but it is well worth it! There are some remarkable photos; my favorites include the Marine Iguana, the Galapagos shark, and the Stone Scorpionfish (which looks like something from Star Wars). Mark Blum specializes in underwater stereo photography, and some of the underwater photos such as the seahare or spotted moray eel really pop out. There are also the Galapagos favorites such as Sally Light-Foot Crabs and Sea Lions. Only a few of the pictures did not work that well in 3-D, such as the brown pelican, or some of the habitat photos, but provided for well-rounded text. Associated with each of the 44 pictures is a useful paragraph that introduces the species or habitat. For example, I did not know that the sex of the Giant Tortoise offspring depended upon the temperature of the nest. A fun book for any age!
