What zoo exhibits you know which are unique in the world? I mean a way of exhibiting animals which is new and not found anywhere else. Just very beautiful and very advertised doesn't count.
One example:
Cochrane Polar Bear Habitat in Cananda has a swimming pool for visitors with view of swimming Polar Bears behind the glass.
Burgers Desert in Arnhem. The only Arizona desert recreated in huge tropical hall, with saguaro cactus, yoshua trees, bighorn sheep, peccaries, bobcats, birds, lizards etc.
