Move over, humans! We're not the only creatures who can invent and use tools to keep ourselves fed, warm, safe, healthy, comfortable--even entertained. Thanks to the careful observations of biologists working in the field, we now know that elephants use sunscreen, long-tailed macaques floss their teeth, assassin bugs use bait to lure their prey, orangutans make pillows, and crows will go sledding just for fun. Who's the clever one now, eh? Join writer Richard Haynes and illustrator Stephanie Laberis for a walk on the wild side and get ready to be astonished, delighted, and amused by this jam-packed exploration. Interested readers will find a map, an introduction, a glossary, an index, and a bibliography for further investigation.
