This is the largest species of frog native to Singapore. This particular specimen, about 4 inches long (snout to vent), lives inside Reptopia's Neotropical walk through exhibit. I don't know if it was intentionally placed there by Zoo staff or found its way in.
@Zooish I was about to ask if this had its own exhibit or if it was in the aviary haha
they find their way in. The adults used to be removed from the enclosure but the tadpoles find their way back in through the sump so it was just a lost cause to keep removing them.
