Observer description: I saw a happy grey seal, including its dorsal surface and the head. Such a beautiful being. Observer notes: It was such an enjoyable experience to see the seal swimming near my home. It was a highlight of my day. I named her Gloria. At first, I thought it was a large piece of wood, but then I realised it was a seal. She seemed calm. Can you please confirm the seal is a grey seal as I may be wrong. Thank you

Observer description: We were on the bridge and a seal popped out of the water with a big fish in its mouth. It was getting carried away by the tide towards central London. It’s head kept going in and out of the water, maybe trying to eat the fish.
