What career path should I take?

I am looking for a career that has to do with animals, I was thinking about becoming a vetenarian but now that I think about it I also want to travel and vetenarians don't really travel much unless I deal with farm animals then yeah but I don't want to deal with does kinds of animals much more with domestic animals and wild life, so I kept thinking and I thought why not follow jeff corwins and steve irwins ( crocodile hunter ) path they deal with wild animals and they get to travel all over the world they get known by others, have conservations to help animals and so on, what kinds of careers are this guys in biologist, herpetology, ect. What courses do I have to take? and if you guys know of any other careers that havew to do with animals and traveling please let me know, thanks
