THE THAMES WHALE, 2018
In January 2006, a juvenile female northern bottlenose whale was found swimming in the River Thames in central London. Approximately five metres long, she weighed about seven tonnes. Her normal habitat would have been on the coast of the far north of Scotland and Northern Ireland, or in the Arctic Ocean. It was the first time a whale had ever been seen in the River Thames since records began in 1913. Sadly, the whale died the next day from a seizure as she was being rescued. Her skeleton is now exhibited at the Natural History Museum.
