What does it take to become a wildlife biologist?

hi there, I once worked with wildlife biologist and they get their degrees in bachelor of science in biology and majoring in terrestrial biology or marine biology. And when they graduate they work as a researcher for the biologist because they still have to take up masters in biology and have lots of papers and researches before they are called a biologist and they have affiliations with organizations that have focus on flora and fauna or conservation. But you can still enjoy the wildlife without being a biologist like me. I worked for an environmental organization and assists the bilogists in counting some fruit bats and even tagging them and we do bird watching. Now, I volunteer for organizations that focus on marine conservation. There's wildlife under the sea, just think of fishes and sharks ... hope I don't encounter one.
