A look into a unique ecosystem, one that is endangered in many placesA seed is jostled from a branch of a mangrove tree and floats to a lagoon in the Caribbean Sea. It takes root, sprouts leaves, and slowly begins to grow. Over many years, the mangrove will provide a home and nourishment for numerous creatures of land and sea. Among its roots come to live fiddler crabs and shrimp; in its branches dwell lizards and hummingbirds. Soon the tree is dropping seeds of its own, and other mangroves are growing, creating a tangle whose benefits extend even to large mammals like dolphins and manatees. There are endpaper maps that indicate where mangroves are located and the names of common animals and plants found in them.Ever threatened by hurricanes and even more by human destruction, the mangroves of our planet are endangered, but in Lynne Cherry's richly illustrated story one such habitat survives, giving readers hope and inspiration for preservation of these ecosystems in the real world.
