| Format: | "When Nature Calls draws on scientific research to show readers the role poop plays in the animal world. Some creatures use it as a weapon; others count on it to communicate; and there are animals whose frass, or dung, or waste, helps the planet. From birds to bugs to mammals, this humorously illustrated compendium is paginated, and contains an introduction, a conclusion, an author's note describing the research process, an index, and a list for suggested reading on related subjects. Pages contain profiles of each animal's poop properties, and sidebars highlight special information about those properties."-- |
