This is the kind of stuff that kills me and makes me want to do it so BAD!! Where do you work? because i see that you have been to myrtle beach i am going to be there at the begining of august.. i was going to look into job shadowing a marine biologist or something like what you do?
lol, easy there killer. All that was past tense, right now I'm selling insurance for the family business, not sure that's gonna help you out any. I have not worked at Myrtle, but yes, I've been there quite often and have some friends there that work with all kinds of animals.
Like I said before, try to figure out what the differences are between jobs so that you can narrow it down as to what would suit you better. Just do some work on a search engine, I'm sure you can find some sort of job discriptions. Marine Biologist/Zoologist tends to relate more towards someone doing field work/research, although I do have a BS in Zoology. There are keeper positions which are more husbandry related with minimal training, and there are "trainer" positions which are a bit more hands on, but also more dangerous. You also have to consider availability, as someone else already mentioned, pay, how much you enjoy weekends/holidays (because you sure are not going to be seeing those, lol), social life, how physical you want work to be, etc... Remember, when you watch an animal show you see 30 minutes of that life, and we wouldn't dare show you the bad, thats the best.
But first, I think you should focus on what you want to study in college and the differences between majors. There are so many that can lead you to the same place. Do you like all animals, just the ocean, animal behavior, companion animals, phsycology, etc? All these have different majors, but can all get you to a nice training position. College is going to be a big chunk of life, and if you are miserable in what you are studying it isn't going to be fun. If you don't make it out or do well, chances are the only job description you need to know is volunteer.
... and I don't think you want to shadow me, unless you want to know all about the wonderful world of insurance:spin2:. If give then chance I would do it all the same, but there are reasons that I quit.
Like I said, if you have any questions, I would be happy to answer them...
