@Cyathea I saw Asian leaf turtle (Cyclemys dentata), Philippine sailfin lizard (Hydrosaurus pustulatus), Luzon mangrove snake (Boiga dendrophila divergens), Emerald tree skink (Lamprolepis smaragdina), Polillo false gecko (Pseudogekko smaragdinus), Gray's monitor (Varanus olivaceus) as well as free-roaming butterflies the day of my visit.
The main star of the greenhouse is the Philippine crocodile (Crocodylus mindorensis), which was sadly a no-show when I was around. I have seen them before at the London zoo, but I was looking forward to seeing them! There is also a few more reptiles I didn't see and didn't take pictures of their signs of, maybe other members will be able to offer a more complete answer.
