London

Observer description: Dark head sticking out of the water, initially thought to be a buoy though after watching for longer and seeing it move could identify the head shape, very dark and more angular head so concluded was grey seal, unable to see full body shape as Thames was very brown

London

Observer description: Head and back. Nostrils above water and whiskers were clear to see. Black eyes. Smooth head. Back was slate grey and smooth. Observer notes: I was surprised to see it at first. I saw it for less than a minute. It was facing north just above the surface of the water. I assume it was breathing air in before diving down again.
