See this question asked by someone who wants to be a whale trainer. I think dolphin training and whale training both fall under Marine Mammal Trainer, so the info might also be useful to you. As well as education you should also work on getting as much hands-on experience as you can. Maybe try to volunteer at a Marine Animal Rehabilitation Center.

http://www.bsu.edu/biology/article/0,,31988--,00.html Careers in zoology span a tremendous range of biological subdisciplines, from systematics and taxonomy to physiology and biochemistry to ecology and behavior—all connected by the subject of study: animals.
With a zoology degree, you could work in teaching institutions, industry (food, health, pharmaceutical, agriculture, and biotech), government agencies (e.g., environmental protection, food and drug, fish and wildlife, land management agencies, park services, water quality, and agriculture), as well as zoos and nongovernmental conservation organizations.
