This is the new lemur exhibit, which is a bit on the small side. It previously housed Coatis.
There was soap on the glass since the lemurs were still getting used to this space, but a rude visitor eventually wiped a bunch of the soap off to get a better view of the animals.
@StoppableSan The difference is that the Black and White Ruffed Lemur exhibit is substantially larger than this one. For the Collared Lemurs, essentially the entire exhibit is visible in this single photograph.
@lintworm Even as an indoor lemur exhibit there are far better ones from what I've seen in Europe - even Marwell's indoor lemur exhibits are better than from what I can see here ...
Even for coati this doesn't look very impressive at all.
