Arms twist and twirl ... Suckers stick ... Meet the octopus! Brimming with vivid photos and scientific facts, this middle-grade nonfiction book treats researchers and sea animal lovers to a comprehensive profile of these impressive invertebrates of the ocean. It covers zoology topics such as anatomy, diet, habitat, and life cycle, as well as species conservation efforts and the ocean animals' relationship with humans throughout history. Sidebars, a range map, and a glossary support the main text, while a Pacific island myth from Kiribati about the octopus adds a cross-curricular cultural layer to the title.
