Rhampholeon acuminatus.
I don't know how many are on show in this refurbished exhibit. I know what I was looking for, but it took me several minutes to spot a tiny tail waving between the leaves. After another couple of minutes, this head took its place. It was easy to see another in the second exhibit in the Amphibian Ark, because it was resting against a mesh screen behind the front glass - which made it impossible to photograph.
I recommend the zoo's video about this species and its new exhibit, presented by a trainee keeper
