This book is suitable for ages 8 to 12 years. The incredible beauty and biodiversity of the coral reef is brought to life in this expandable accordion book that stretches out to provide a 3-D view of a multicolored undersea world. A look into the tunnel reveals clownfish hovering over a field of anemone tentacles, a spotted moray eel poking its head out from its hiding place, and the countless other sea creatures inhabiting this magnificent, endangered ecosystem. A 16-page guide to the fish and corals of the reef is also included.
