Sleek body darts ... Forceful jaws snap ... Meet the eel! Brimming with vivid photos and scientific facts, this middle-grade nonfiction book treats researchers and marine animal lovers to a comprehensive profile of these fascinating fish of the sea. 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 ancient Greek story about the eel adds a cross-curricular cultural layer to the title.
