Ages 5 to 8 years. This is an introduction to the interesting plants and animals young readers can find in and around the Chesapeake Bay and its tributaries. With outstanding illustrations and concise text geared for children ages four through nine, the book beckons youngsters and their parents to learn by exploring the estuarine environment. On a stroll through its pages, they can see soft-bellied bullies, crabs older than dinosaurs, and "bald" five-year-olds. Chesapeake Bay Walk guides readers along the bay's different shoreline habitats: beach, mudflat, pier, marsh, and shallows. It features an explanation of the food chain that is easy for this age group to understand, a tour of the changing seasons, and a checklist for youngsters to use to keep track of their discoveries.
