A Whale Is Not a Fish and Other Animal Mix-Ups

I like this book mainly because it went to extraordinary lengths to explain why a whale isn't a fish or the differences between a crocodile, an alligator a frog, and a toad. The thing that surprised me the most is finding out the difference between a donkey and a mule. I never knew that mules couldn't reproduce. I did know that they were stubborn. I also didn't know that there was such a thing as the butterfly moth.All in all, I found this book entertaining to read and would recommend it to young readers.
