Whale spotted in central London

BBC NEWS England London Whale spotted in central London: “A large whale has been spotted in the River Thames in central London by boaters and sightseers.

The mammal, thought to be a pilot whale which can grow to 20ft, was seen swimming past the Houses of Parliament. “

Not much of a pilot then, is it?
I’ve just seen the video footage of the poor whale. He seems quite desperate to swim further upriver.

Update: Seeing the footage reminds me pleasantly of seeing the pilot whales off Teneriffe last year, where we saw a whole school (is that right) of them.
