'''Endangered Species''' is a [[Achievements in GTA IV|trophy/achievement]] in [[Grand Theft Auto IV]]. It is not story related, so it can be missed while playing the game.
You acquire this trophy when you've found, i.e. killed, all 200 [[Flying Rats]]. The easiest way is to use a map found on several websites, including this wiki.
