There was a pitch black exhibit at the Vancouver Aquarium that had a number of black objects flitting around in it. Upon closer inspection, I realized it was an exhibit on fruit bats. This is new or at least it is new for me as I hadn't seen it last time. Given the darkness, I needed to use the flash. I hope it didn't scare them. I had no idea what I was photographing until I looked at the screen. Anyways, if you are in the Vancouver area, I recommend a trip to the Aquarium.
