Long claws cling ... Sleepy eyes stare ... Meet the sloth! Brimming with vivid photos and scientific facts, this middle-grade nonfiction book treats researchers and wild animal lovers to a comprehensive profile of these slow-motion mammals. It covers zoology topics such as anatomy, diet, habitat, and life cycle, as well as species conservation efforts and the rainforest animals' relationship with humans throughout history. Sidebars, a range map, and a glossary support the main text, while a South American myth about the sloth adds a cross-curricular cultural layer to the title.
