Apologies for the poor quality, but you can see the animal in the center of the photo.
I actually got lucky here because the aye-aye exhibit was closed due to the female being treated for an injury. Fortunately, I bumped into a keeper, who allowed me to quickly follow her to check the nocturnal primates out. I was awe-struck and very grateful for this lucky chance to see this species for the first time in my life.
