Zurich has 3 areas with a strong freshwater theme, plus a few other species spread across the zoo. Selenga is a large walkthrough enclosure with a good selection of Eurasian waterfowl, Grebes, Cranes, Storks and European pond turtle. This is a quiet corner of the zoo, but still very well executed. Pantanal has a large mixed exhibit with Lowland tapir, Capybara, Giant anteater as well as Southern screamers. In addition there is a large breeding colony of Chilean flamingo and a multiple species of S-American waterfowl. The area also includes islands for Squirrel- and Capuchin monkeys, but they wouldn't count for this challenge. The Exotarium has several nicely landscaped (but not huge) aquaria for several freshwater species, with tanks for Pirana, Electric eel, SE Asian species and Malagasy species. The terrarium section has two enclosures with plenty of water: one for Philippine crocodile and the other with Yellow anaconda. On the outside is an aviary with Scarlet ibis & Boat-billed heron and there are several bird species in the house which fit the wetland theme like Wattled jacana and Red-and-white crake. Then there is a large variety of Malagasy/African waterfowl and African jacana in the Masoala hall (with yet more endemic fish species), Small-clawed otters in a further unthemed enclosure and a European otter enclosure with adjacent an aquarium with native fish, and an aviary with Eurasian spoonbill. Overall Zurich has 2 well executed thematic areas focused on freshwater, plus a variety of other freshwater species around the zoo.
