A Caldecott Honour-winning duo draws inspiration from graphic novels to bring symbiosis to life in this stunning non-fiction picture book. How to Clean a Hippopotamus, a book about animal symbiosis, offers readers a close-up, step-by-step view of nature's fascinating partnerships. Find out why a mongoose comes running when a warthog lies down, how a crab and an iguana help each other out, why ravens follow wolves, and more. Witness the ingenious lifestyles of some of the world's most unusual animal partners in this book of curious biology, a symbiotic collaboration by Steve Jenkins and Robin Page. AUTHORS Robin Page and Steve Jenkins share a burrow in Boulder, Colorado, where they work and forage together, occasionally picking lint off each other's sweaters. They enjoy a happy host/parasite relationship with their ten-year-old son Jamie. Their two other nestlings have fledged. REVIEWS "These fascinating stories from the natural world will easily interest young people, many of whom will want to move on from the appended notes about each featured critter to more in-depth titles that further explain the mysteries of animal symbiosis."--Booklist, starred review ILLUSTRATIONS Full-colour Ages 6-9 *
