This book was amazing!! it is filled with pictures on every page. The book is divided into 4 sections. When i started reading the book i didn't want to stop!! I wanted to know more and more about that animal. Like do you know how big the smallest bat is?? What reptiles scales are made of??? How to tell the difference from a spider and a tarantula???? If you wanna know you have to read this book i recommend this book to any one interested into lizards,bats,spiders and snakes. i give it a 5 out of 5 rating!!
