This book explores what makes whales different from all other underwater creatures. It addresses some myths and misconceptions of whales and gives facts about these creatures. It discusses how whales have evolved over millions of years, it talks about their daily lives, puts these creatures size into perspective, and explains how to tell the difference between 10 different types of whales. The book is broken into two sections. The first section discusses the common attributes amongst all whales. The second section talks about each kind of whale one by one. I would use this book in my classroom to give to a student who is really interested in whales or if Iwere teaching a unit about mammals or underwater creatures.
