The ocean covers almost three-quarters of the Earth, but how deep does it go? Put on your scuba gear and explore the different ocean zones, from the sunlit shallows to its deepest, most mysterious parts. As you dive deeper, you'll discover glowing animals, strange creatures that don't need sunlight to survive, and even the largest hunter in the world.

With beautiful illustrations and engaging text, How Deep Is the Ocean? will guide young readers into the deepest parts of the sea. Featuring fun, hands-on kids science experiments, a water-pressure test, a lesson in making a sounding line, a glossary of new terms, and web research prompts, this book is a perfect introduction to marine biology for kids. Both the text and the artwork were vetted for accuracy by Dr. David Gruber, real-life deep sea explorer and professor of biology and environmental science at Baruch College.
