Can you give me some good careers?

I love working with animals especially marine animals. Not as much marine mammals though. I'm thinking about being a Marine Biologist or Marine Ecologist. I want to study marine animals and do some general research and help conserve reefs and underwater environments. I also may want to be a Marine Conservation Biologist. I want to work in an aquarium so can anyone give me a good list of careers involving lots of interactions with marine animals. I want to be able to research marine life to figure out ways to conserve ecosystems and help fish. But I think I want it to be in Marine Biology or Ecology. Thank you in advance!
