There are thousands of kinds of fish. From bass and yellowtail in the Great Lakes to the many sharks of Earth's oceans, they all seem like very different animals. But, all fish live in water, breathe with gills, and have fins to help them swim! In this book, emergent readers find low ATOS text describing what makes a fish, a fish. Full-color photographs show body features close up that readers might not ever see otherwise. Close text and photograph correlation aid in comprehension.
