When Nature Calls: The Unusual Bathroom Habits of the World's Creatures

Series:

Some creatures use poop as a weapon. Others count on it to communicate. And there are animals whose frass, or dung, or waste helps the planet. There are even creatures that don't go at all: a South American scorpion just discards its bum -- never to poop again! From birds to bugs to mammals, When Nature Calls draws on scientific research to show readers the role poop plays in the animal world.
