Pongoland includes Western Lowland Gorillas, Bonobos, two groups of Chimps (mostly ssp. [i]verus) and a mixed exhibit of Sumatran Orangs and Gabri[/i]ella's/Buff-cheeked Gibbons. The exhibits are all broadly similar (though the Asian apes have rather more climbing).
The moats are full of frogs, as well.
