NASA calls the ocean the "great unknown," because we know more about the surface of the moon than the bottom of the ocean. Marine biologists study marine life by swimming with sharks or learning about life processes by studying plants that grow with almost no sunlight, making them some of Earth's greatest adventurers. With explanations about how one becomes a marine biologist and the many different paths their careers might take, this book is perfect for readers who are adventurers, animal lovers, swimmers, or simply curious about what's under the water that covers 70 percent of Earth.
