If you've ever tried to shoot photos at an aquarium, or even through glass, you'll know how hard it is to get anything decent. The odds are stacked against you: glare! depth of field! death by autofocus! This shot was the best of several dozen taken at the Aquarium of the Pacific in the Jelly exhibit. Jellies are mesmerizing and photogenic, and it's hard to not at least try to get a shot of them. These guys were about 4-6 inches long. Unfortunately, I don't recall the species.
