Oooo, you could work at a big aquarium. And that way you could get to study each one pretty personally.
I also like the marine biologist and icthyology suggestions. You should get scuba certified!
well! you can be a marine biologist which is the study of salt water fishes and marine life. you get to visit oceans around the world. Help endangered whales, sharks, fishes and much more and get hands on. If your going to to college then you should take with road. GOOD LUCK!
