Biodiversity in the ocean is critical to the health of the planet, yet very few texts are available that explain the variety of aquatic food chains. Through appealing photography, clear text, and engaging design, Life Cycles: Ocean by Sean Callery examines one lifecycle in each of three oceans-The Indo-Pacific Ocean, The Pacific Ocean, and the Atlantic/Indian Ocean. At the end the three cycles are woven together into one food web, demonstrating that all life in the ocean is linked. A wonderful introduction to an environmental topic that is at the forefront of current events.
