The ocean is big, blue, and beautiful, but there is so much more to it than what humans can see from the coast! About 71 percent of the Earth's surface is water-covered, meaning there is plenty of sea that has been explored and plenty that hasn't been. In this book, readers dive into the oceanic world, learning about the sea and the many creatures that live there. With full-color photographs and vector images that have readers feeling as if they're swimming alongside sea creatures, this book will engage readers from start to finish.
