Did you know that sharks produce spiral poop? That the average Japanese woman uses 2 1/2 miles of toilet paper a year? That when wolverines are done feeding on a dead animal, they save the rest for later by defecating all over it?

Those gross and fascinating facts can be found in "The Truth about Poop," an informative and funny book that will take readers from life before toilet paper to the most modern toilets, from poop games to poop used in warfare, from cow chips to insect droppings. Acclaimed nonfiction author Susan Goodman covers many facets of a subject children just love to read about, and Elwood Smith's humorous illustrations add a lively slant to a book that's already brimming with fun and information.
