Is this the Wharf's legendary Sammy The Seal?
The photograph was sent in by Dai Taylor of canarywharfphotography.com and taken from its studio near the Prospect Of Whitby pub in Wapping at the weekend.
Sammy is a regular sight for workers at Billingsgate Fish Market - where unsurprisingly he is a regular - and by Barclays staff outside of the Churchill Place headquarters.
The grey seal posed for this long distance shot when he heard a camera clicking.
Reports of lone seals being spotted go back as far as 2004 and are used as evidence of a recovering ecosystem in the Thames.
