@drill However, since it's been brought up, here's what I've gathered from obvious observations and from the clips of signs I received as well.
1. Harpy Eagle
2. River Bass
3. Red-bellied Piranha, Cardinal Tetra, Polka dot Stingray, Motoro's Stingray, Armored Catfish, Bucktooth Tetra, Dwarf Cichlid
4. Giant Otter
5. Baird's Tapir
6. Southern Black Howler Monkey (That may or may not still be together with Pacas)
7. Bald Uakari
8. Crested Oropendola, Sunbittern (May contain a Magpie jay?)
9. Dwarf Caiman, Mata Mata
10. Golden Poison Dart Frog, Blue Poison Dart Frog, Bumblebee Poison Dart Frog, Splash-backed Poison Dart Frog
11. Marine Toad (Not mentioned because apparently they're never visible or on display)
12. Keel-billed Toucan
13. Jaguar
@Moebelle I'm going to be completely honest: I don't know. I know one died, but it's still have the species on the website so I guess maybe they have another one? However after looking at several videos and pictures on the internet, I only ever see one.
