Gr 3-6-Many young readers won't know that sloths only eat leaves, and move so slowly that a special type of algae grows on them. This book combines that kind of detail and scientific research with stunning photography to serve up fascinating information about these sometimes mysterious, sometimes adorable creatures. QR codes throughout the book give readers access to videos of sloths doing sloth things-as a baby, chewing a leaf, yawning. After a brief history of Dr. Becky and why she embarked on a sloth study, the focus is on the unique and slow-moving world of sloths. Throughout the book, conservation and protection of sloths remain the overarching goal. Maps and photographs are included with basic facts and fun trivia. A glossary, further reading , websites, and index are included. VERDICT Overall, a delightful addition to any library, helping readers not just to understand sloths, but to understand why safeguarding them and their habitats is critical.-Amanda Chacon
