@DavidBrown Manatees, arapaima, sloth, pygmy marmoset. I think maybe additionally white-faced saki and some birds. There are other species in the water as well.
This is one of those exhibits that really makes you wonder why every major zoo isn't doing something similar. And of course some are: this year I have seen Burgers' and Nurnburg's manatee halls, which are both (I think) even better in their own ways.
