How does the sea carve a coastline? How do mangrove trees, puffin birds, and sea anemones thrive along the ocean’s edge? Life on the Coastlines by World Book's Ecology series engages middle readers from grades 5 to 8 with fascinating bits of coastal lore. The richly illustrated book also describes how some coastal people make a living from the sea and seek to protect this special environment. The book includes a story about a mermaid legend, a fun quiz, and a helpful glossary.
