Max and Phyllis, the Pygmy Hippos (Hexaprotodon liberiensis) at Chester Zoo in 1975. This enclosure was the outside accommodation for the hippos who also had an indoor area underneath the Nocturnal House. This site now houses the capuchin monkeys.
The new savannah in Copenhagen Zoo, right before it opened in June 2007. That's also why the grass still is so green, since both rhinos and zebras will live here. Behind the wooden wall to the left, the new hippo house was being constructed at the time. The species living here are zebras...
The large inner hippopotamus enclosure at Zoom Erlebniswelt in Gelsenkirchen, Germany.
They have a large outdoor facility and two small inner enclosures as well.
The plan for the new Hippo House at Cologne Zoo. This is the next big project, and is supposed to be finished in 2010. The house will be the home of common hippopotamus and nile crocodile.
Flussferd = Hippopotamus
Gepard = Cheetah
You can figure out the rest ;-)
