Jelly at Aquarium in Newport, Oregon, USA (or Some People Call Them Jellyfish)
I took this with a sub-megapixel camera when digital was first getting started. I think it came out pretty well, considering. Even though I now know jellyfish is incorrect, I have called them that for over 50 years, and sometimes still do.
For Snap Game on July 2, 2007 a snap from a spiny crab (very spiny, I might add) to a jelly with "no spine" at all. Both from aquariums, but different ones.
