To remove all doubt,this was taken in an aquarium. I have enough trouble making photographs without having to remember umpteen details of depth, buoyancy, breathing, etc.
I’d just finished telling my girlfriend that the chances of seeing an otter were slim to none – especially if she kept asking loudly – when this cheeky fellow came running hard and fast from a pair of blackback gulls (I suspect he had been raiding the nest), and so somewhat less cautious of two large bipeds pointing a nikon at him.
This finch caught my eye in Aberdeen. He was only there for a second or two before disappearing high up into the tree.
