1. Prague-
2. Schmiding Zoo's Aquazoo- which has a separate entrance fee/closing time and is where the Santarem marmosets are kept.
3. Valencia Bioparc- in September although normal Zoo hours go until 7pm, tickets normally stop being sold at 6pm, but they allowed me to buy a ticket at 6:10 after driving 4 hours from Madrid. (So should still count for my carnivore challenge but let me know if you think otherwise). I hope to getting around to a proper write up of my trip to outline the drama a bit better haha.
@ThylacineAlive Yes I understand your reasoning with Prague.
And the Santarem are a very recent addition- I think they had only been on exhibit for a couple weeks, and likely the only pair outside of South America. I was similarly lucky with my timing for the Javan Ferret Badgers at Brno, which had only been on exhibit for about 1 week when I arrived.
