eSource: Comparing Animal Traits

The Comparing Animal Traits series builds students’ critical thinking skills by helping them gather and analyze information about what makes animals similar to and different from one another. The clear text and vibrant photos show how some species in the same animal group—such as mammals—have similar traits, while other animals in the group vary widely in appearance, behavior, habitat, and life cycle. In each book, readers compare and contrast traits of the main animal to several other animals, drawing conclusions about how they all fit into the same animal group.
