It's pretty well known that the enclosures in the Terrarium vary pretty wildly in terms of quality, however many of the better ones do belong to their "island" species. Annoyingly there aren't many photos of these on the forum but I included what I could find below:

Part of the Komodo Dragon Enclosure - Wroclaw Zoo Terrarium - ZooChat (animal in upper right corner for scale)

The zoo also has a great Madagascar house, which includes both a walkthrough aviary and separate singular enclosures. I believe there's an outdoor aviary as well:

Unfortunately after the above there don't appear to be any photos of the enclosures for their mammals, other birds, herps, or fishes which is quite annoying. The echidna enclosure is rather spacious with plenty of logs and mulch for them to hide under. The zoo has a very nice aquarium for small freshwater fish as well.
