I like all wildlife....when I was younger I wanted to be a veterinarian, or a zoologist, but the only reason I didn't is because I learned how long you have to be in school for it, and how little you make compared to my current path of choice.
I always tell myself when I am done raising a family I will pursue my personal passions, whether that happens or not is another story, I will have to check in on that theory in about 10-20 years.
