In a new, exciting series called "Introducing Habitats," Kalman and various writing colleagues take on some complicated issues by describing plants and animals that live in various habitats, why they live there, what is special about the place, and of course, what a habitat is. "A habitat is a place in nature," we are told in the first sentence. And later, after introducing the living and non-living things that are there, we learn "Animals find everything they need in their habitats." Using stunning photos for illustrations, Kalman and Aloian move into a marsh, explaining what it is, examining the plants and animals that live there and what kind of special adaptations they have to live in or near the water. The writing team also discusses plants and animals in broader terms, explaining photosynthesis and food webs. While they limit the types of wetlands described to marshes, the animals shown include creatures from several continents. Each page has fewer than forty words of text. The text refers to the pictures used so no captions are necessary. With the clear writing and wonderful pictures, this book will serve the young, informational reader well. Back matter includes a short glossary and an index.
