What strange-looking creatures inhabit our planet? Young readers can find out with the Curious Creatures series (6 titles), each volume of which spotlights a mammal with unique, eye-catching features. Over the course of several short chapters, each book establishes a strong base of information on its unusual subject. The first chapter provides a scenario showing the creature “in action” and then introduces its most distinctive body part. Elephant Seals highlights the trunkish noses of these blubbery behemoths. Additional chapters address the animals’ food and habitat; their young, family or group life, and growth; and the threats they face from humans. Throughout, large photos emphasize the animals’ unusual physical traits. Plentiful, simple infographics also make the books’ facts easy to understand. Fascinating statistics are found in a two-page, illustrated “By the Numbers” section covering everything from the size of the animals’ unusual body parts to the age at which females can reproduce to the animals’ typical lifespan. A glossary and “Learn More” resource list round out the back matter. An interesting and informative peek into the lives of some of Earth’s unusual inhabitants.
