Shaffer does an excellent job in describing the life cycle, habitats, behaviors, and threats of the different types of bearded dragons.  I actually learned a new word from the book, brumation, which is the precursor to hibernation when appetite decreases and body temp falls.  The photos are spectacular and show the textures of the dragons’ skin and nails.  This book would make an excellent resource for any research project and should be included in a library’s collection.
