This is a little nonfiction book from the Pebble First Guide series. I always like the set up of these books. This book focuses on nocturnal animals such as bats, crocodiles, eels, fireflies, frogs, etc. Thirteen nocturnal animals are introduced in a basic field guide format. Each animal is showcased in facing pages with 2/3 pictures, a map, and characteristics (length, weight, what it eats, where it lives and some facts). These are great little books, easy for little ones to read with the format and have great pictures. I just always wonder about the size. They are pretty small and they get lost in the shelves pretty easy.
