This is the latest sign of alien activity in the skies above Merton.
The picture was taken by Nicholas Fitter, from his flat on the Broadway last week.
Mr Fitter said: "I was doing my laundry when I saw it.
"I thought it was a balloon at first, but it was as big as a house. I went out on the roof and took some pictures.
"It had tentacles that appeared squid like and even mimicked a squids movement at times. I am sure other people would have seen it too since this jellyfish appeared rather large in broad daylight."
