Each of the featured species is the largest in its group. Capybaras, for example, are the largest rodents and the Japanese spider crab is the biggest arthropod. Height and sometimes weight are noted, both at birth and full-grown stages, and occasionally compared to other massive animals. The bulk of the text, though, focuses on life cycles and habitats. Every page includes a large photograph; some of these use captions to highlight key features or add extra facts. The use of a large font, with key sentences sometimes printed in different colors, adds some visual appeal. Endangered status is noted when applicable. A simple labeled body diagram and additional fun facts appear in a final spread. VERDICT Solid animal profiles where subject coverage is needed.
