@Maguari Prior to the title of the photo being changed it was titled as a species that Dudley has never held. A species which the poster subsequently claimed it was labelled as, which I'm certain it isn't.
I can't remember that or have an image so don't think it was that as I only added titles by signage I took while taking the images and when I download to external hard drive I put images in to folders then the signage into a different folder.
Just going through my signage for this visit and have come across Madagascan tree boa image to which this could have been the signage to the left of the exhibit
If it was Madagascan tree boa then the zoo has held them for many years (I thought it had been titled as something else).
Everything is usually labelled correctly, but I agree that the positioning of the signage can be confusing, especially if there are two species next to each other that at a glance can look rather similar.
