A rosy wolfsnail prowls along a hosta leaf, finding and devouring its prey—another snail. In this introduction to a carnivorous species probably unknown to young readers, striking color photographs of larger-than-life-sized snails accompany a simple straightforward text. Native to the southern United States, wolfsnails have been introduced in Hawaii and other parts of the world where they have become a serious pest. This photo essay, however, concentrates on the animal itself—its curiously shaped head, its ability to follow a trail of slime or hide from a predatory bird, the toothy tongue that allows it to remove the meat from inside a smaller snail. Backmatter includes a list of fast facts, additional information (including mating and reproduction) and a glossary. Sure to encourage early readers and listeners to explore their own backyards for similarly wondrous creatures. (Picture book/nonfiction. 4-7)
