These bizarre jellyfish-like beings is what aliens would look like, if they exist, a British scientist has said.
This is what evolution might have come up with on a world such as Saturn's moon Titan, Dr Maggie Alderin-Pocock believes.
She envisages creatures that float through clouds of methane, scooping chemical nutrients into their gaping mouths.
The aliens keep themselves aloft by means of dangling onion-like buoyancy bags, and communicate with pulses of light.
Her aliens would probably die on Earth, finding the damp oxygenated atmosphere lethally corrosive. Equally, humans would not survive on Titan.
Based on the latest discoveries of star-orbiting planets, she also believes as many as four intelligent extra-terrestrial civilisations could exist in our galaxy, the Milky Way.
But they are so far away it is unlikely we will ever meet them.
Dr Alderin-Pocock presents Do We Really Need the Moon on TV channel Eden today at 7pm.
