Wide flippers flap ... Big tusks protrude ... Meet the walrus! Brimming with vivid photos and scientific facts, this middle-grade nonfiction book treats researchers and wild animal lovers to a comprehensive profile of these bulky marine mammals. It covers zoology topics such as anatomy, diet, habitat, and life cycle, as well as species conservation efforts and the animals' relationship with humans throughout history. Sidebars, a range map, and a glossary support the main text, while an Arctic folktale about the walrus adds a cross-curricular cultural layer to the title.
