As I was in a confference at the zoo, I only had time to pay a very quick visit to the amphibian house, so I didn't photograph all the signs to be able to remember properly now, buy I'm pretty sure I saw many species of endangered brazilian frogs, specially the Alcatraz tree frog. There were also several members of the bufonidae family, as well as a pair of axolotl in the last tank. All the enclosures were pretty well planted and quite spacious for their dwellers.
