Doing the research and doling out cash for a license are two different things.
That doesn't mean everyone who's ever got a piece of paper saying they're a "Zoologist" doesn't do any research. There will obviously be at least a few credible Zoologists coming out of the education system. Are you that untrusting? really?
I mean, it's better than some guy who watched Teen Wolf as a kid, grew up and joined a bunch of others who want to tell spooky stories out in the woods. How is he gonna know anything about habitats or food sources?
