This footage was filmed and produced 30 December 2022.

This is Thor the walrus, who caused New Year's Eve fireworks to be cancelled at an English seaside town, as he leaves the UK to head north to colder waters.

His arrival also meant a long vigil for members of the British Divers Marine Life Rescue (BDLMR), who stood by to make sure he was not disturbed by revellers before heading back into the water to continue his journey.

The video was shared by Em Mayman, an assistant coordinator for the BDLMR. She said: "I'm 32 from Yorkshire, I work at a vet's as a day job and volunteer for BDMLR as an out-of-hours coordinator and assistant area coordinator for Yorkshire and Lincolnshire. I recorded the video in Scarborough when Chris Cook and myself were called to check it out. As area coordinators, we needed to get down there to see what was going on and plan the BDMLR response. We've not had a walrus in this part of the UK in a very, very long time. There have been dozens of sightings in the UK in the last 150 years, but we have now had confirmed sightings of three in just two years. Wally who eventually returned home in 2021, Freya who met her very untimely demise in Norway, and Thor. Thor is a young Arctic walrus at sexual maturity, around eight years old, and has been travelling between the UK and Europe over the past few months. At present, he is in good condition with no injuries."
