School Library Journal

“Heos’s humorous, chatty introduction to what crocodilian parents do to protect their eggs and hatchlings until the offspring are able to take on their own predatory roles is evenly orchestrated through Jorisch’s hilarious line drawing and watercolors….The information is delivered to the crocodilian parents in a Q&A format: amid heavy personification, there is a good deal of material suitable for use in reports.” —School Library Journal

Science Books & Films

“The life cycle of members of the crocodilian family is cleverly and humorously described in this delightful book. The informative text, framed in a ‘Q and A’ format, encompasses many pertinent facts about alligators, crocodiles, caimans and gharials and flows easily from one area to another. Habitats are described, best sites for nests are noted and the developmental cycle within the egg is skillfully outlined. After the hatchlings appear, the text describes parental care, predators to be aware of, and when the young are mature enough to ‘leave home.’ Colorful and whimsical illustrations add greatly to the book.” —Science Books & Films

Kirkus Reviews

“Both engaging and informative, this is a welcome addition to a kid-pleasing series.” —Kirkus Reviews
