Okay, so I have have made a list of what mammal species and how many individuals, I would like to have in my dream zoo. This is a long list, with over 500 species, most of the species exists in captivity today, some dont, but anyway this is just fantasy. I am working on a bird list too, but I will may take a couple of weeks before it is finished. Other people can post their dream zoo animal list on this thread as well.
