Zoo Tycoon: Ultimate Animal Collection

This is a pretty self-explanatory achievement. Just need to release one of every animal into the wild, including those in the small exhibits. Because it only requires you to release the original animals, it may cause some confusion as to which ones. Here is a list of all the animals you need to release. You can do this as soon as they turn level 15:
