This exhibit is really great: the lemurs are separated from the zoo guests by a glass window. A couple of them are super interactive!
Terrestrial algae growing on the front of a golf cart. I don't know even how to begin trying to identify this organism more specifically, but these people seem to be working on it. I suspect I'd need a microscope and a whole lot more book learnin'. Also, I think I have a crush on the phrase "aero-terrestrial algae." ("Part of the aero-plankton.")
