Have you ever heard of a potoroo? How about a vaquito? Maybe the reason why you haven't heard of them is because those animals are extremely rare and likely quite endangered. The WWF, that's the World Wildlife Foundation (not the World Wrestling Federation), is very involved in doing all it can to help prevent species extinction. If we lose an animal to extinction, then it's good-bye for good, so it's important that certain things are done to save species before they cease to exist. This quiz will test your knowledge about a bunch of animals that are extremely rare and/or endangered. Many of them are found in only one place on earth! Let's begin.
