Thank you, John.
Sorry to be tardy in replying to your comments on this and another thread, but I haven't visited this forum for a year or so due to long illness - followed by my switch to Sony (A7Rii). However, I very recently got around to setting up a POTN Gallery, not realising that it would result in an embarrassing flood of images from old threads returning to public view.
Yes, the Penguin Oyster shell and its reflection is very suggestive of a dolphin, whilst the Ficus Gracilus could be many things – a duck will do. A duck and a dolphin getting together – there's a thought!
