A video is worth a thousand pictures thus a million words: If wonder if it's the largest tapir enclosure (as well as rhea's, coypu's and jabiru's) in the world. What about semi-aquatic in general?
Hello! I'm from Belo Horizonte, Brazil. Yes, the zooparque Itatiba's tapir mixed exhibit is the largest in the world, according to the own zoo crew.
Poznan Nowe Zoo has ca 2 hectares. See pictures: https://i81.servimg.com/u/f81/12/47/11/07/dsc_8417.jpg dsc_8418.jpg - Click to see more photos on ServImg http://cotuduzogadac.pl/wp-content/uploads/2019/06/IMG_9877-1024x683.jpg
I actually don't know how many square meters/hectares zooparque Itatiba's tapir exhibit has... I recently asked the zoo's staff about this question and they confirmed they have the largest one... Don't know, maybe they don't know about poznán zoo's habitat, or maybe their one is largest than 2 hectares...
