A northern bottle-nosed whale has been seen swimming up the river Thames, and has passed by the Houses of Parliament in central London. This species, I understand, resides normally in the Arctic or Atlantic off the continental shelf, so it's appearance in a busy river like the Thames is extremely unusual. It is being closely followed and observed by experts, and there is no sign that it is either weak or sick. If it progresses up river it may accidently beach itself and die, unless some sort of rescue can be made - very difficult with an animal of this size.
I wonder if perhaps it might leave a message near Parliament, maybe engraved on a crystal ball, saying something like 'So long and thanks for all the fish'!
