The volumes in the Backyard Animals series may be slim, but they’re packed with information and include fine close-up photos of critters found all across the U.S. In Salamanders, readers learn that one-third of the world’s salamander population lives in North America. They spend much of their time hiding, and readers are advised never to touch or grab salamanders, as they are easily harmed by the heat and oil of human hands. The series has some unusual features, including myths and legends about the spotlighted animals. Frequently asked questions, a puzzle, and a short glossary round out the able treatment.
