Chances are you won't see these rare animals at the local zoo because their population is down to the last hundreds. In some cases, it's much worse than that with only a couple left. Some of these animals you've never heard of but others on the verge of extinction are related to animals you know and love—like certain types of tigers, frogs, leopards, turtles, dolphins, etc. In 10 years, they might not exist at all. Sad.
