Animals Evolution Avoided [PDF ebook] 
From Gannets to Squids

A humorous book about animals that ought to exist, but never quite made it due to circumstances beyond their control. In this book, you will find the Green Fox, the Straight Snake of Assam, and the Garlic Rat of Alabama. Read about the penguin that provides a back-scratching service to other penguins, the skua that only builds vertical nests, and the snake that hangs from trees pretending to be a vine.
