Marine biologists do more than swim with dolphins--though they may do that! They study how marine life is changing with global warming, how plants in the ocean grow without much sunlight, and more. Since much of the bottom of the ocean has yet to be explored, marine biologists are likely to make some incredible discoveries! This book dives into the career path one might take to become a marine biologist, including the education and experience one would need to succeed. Readers learn pertinent vocabulary terms as well as other key science concepts that have to do with this interesting and fulfilling science career.
