Extremely Gross Animals explores how some of the most effective -- and often truly foul -- survival adaptations in the animal world involve poop, mucus, spit, foul smells and sprays, nasty eating habits, disembodied body parts and zombification. Organized into seven 4-page sections and including more than 30 creatures in all their gross glory, the book is written in an upbeat tone that delights in delivering the dirt on the almost unbelievable ways animals have adapted to survive and thrive. And in addition to appealing to readers' natural interest in this wild world of gross, it also encourages them to think like scientists and appreciate how these animals are as incredible as they are gross.
