List the very rare animals you have seen in captivity - I mean animals that only one or a few facilities worldwide have. Not talking just rare in your area or continent, I mean rare in captivity worldwide. Ok to include subspecies (even if the species is common) and color morphs (even if the typical color is common). Let's keep it to captive animals - if you want to start a separate thread about rarities seen in the wild, feel free. Also, please follow the species name with the location where you saw it. I will post a reply to start things off.
