Paco, Akira and Thomas - many thanks for the kind comments and sharing your impressions!
I had been on a few walks by the shore during that day and spotted several small jellyfish. In the evening I got the chance to take this shot of a larger one from a bridge - I think my mind had circled around such an opportunity most of the day :-) Handheld, 55mm (APS-C) and 1/20 sec. provided a bit of movement in the image.
