I've always had mixed feelings about this enclosure; I guess it works, and it has quite a lot of water when the pool is full, but couldn't they have made it less cave-like? In fact, it would overall make more sense if the walls resembled the roots of giant amazonian trees overall. But as it stands, it just seems like someone put a karstic cave in the middle of the Amazon rainforest and put green anacondas in there.
