Melanie Stiassny. I study life in the oceans, the largest, most diverse habitat on Earth. Below the ocean waves, there live billions and
billions of organisms. There are so many different kinds of organisms in the ocean and so many questions about them that remain unanswered. We know more about the far
side of the moon than we do about the oceans.
To introduce you to the biodiversity in the ocean and to get you started on your investigations, I've picked just a few examples of marine life to show you at least one from each of the major groups that scientists use to classify life on Earth: true bacteria, archaea, protists, animals, plants and fungi.
