If You Are a Kaka, You Eat Doo Doo: And Other Poop Tales from Nature

Baby golden tortoise beetles pile poop on their backs to create a shield as protection from predators.  Silver-spotted skipper caterpillars can shoot their poops 40 times their own body length to conceal their true locations.  Baby hoopoes squirt their poops into the eyes of attackers -- and who wants feces in their faces?  Baby Ozark blind cave salamanders use gray bat guano for food.
The bottom (!!) line: Ever-inventive nature finds a thousand uses for poop.  Nothing goes to waste (!!).  This book is a guaranteed crowd-pleaser with a lot of information to share.
