ALLIGATORS AND CROCODILES

Gibbons’s latest addresses the similarities and differences between two reptiles commonly confused by adults and children alike. Through clear, concise text, diagrams, maps, close-ups and lots of side-by-side comparisons, the author clearly delineates the characteristics that differentiate these two groups. For instance, when their mouths are closed, alligators show only their top teeth, while in crocodiles both the top and bottom teeth extend. Covering their history, geographic areas, body structure, habitat, diet, adaptations, communication, mating, child rearing and threats to survival, this is a comprehensive but accessible look at crocodilians. The prolific author’s signature watercolor-and-ink artwork complements the text, supporting readers in learning the differences between alligators and crocodiles and allowing them opportunities to practice identification. As in her other books, the author eschews a glossary in favor of short definitions on the same page on which the word appears. Similarly, a pronunciation guide follows difficult words as they are introduced. Backmatter includes a page of additional facts and a web address. (Informational picture book. 4-9)
