Fame
You might not immediately equate zoology with rock star fame, but there have definitely been some mega-famous zoologists over the years. Let's see...there was Aristotle, who was one of the first to ever start classifying animals into groups. We all owe him a big thanks for kicking it off. Then there was Carl Linnaeus, who came up with the way to classify every animal on earth. Not too shabby.
Oh, and there was that guy Charles Darwin, whose theory evolution still manages to get some people's boxers in a bundle. Then there was Jane Goodall, who learned everything there is to know about chimpanzees by moving in with them. And let us not forget Steve Irwin, Crocodile Hunter (may he rest in peace), who was famous for hurling himself onto unsuspecting wild animals.
So, yeah, there's no doubt there's the potential to go down in the annals of time as a zoologist. The truth is, though, that most zoologists aren't known outside of their community. You can make huge strides in your particular field, publish tons of articles, and make a huge impact on the world of zoology without ever becoming a household name. If you want an action figure made in your image, you might want to consider professional wrestling.
