Ice worms of Europa and beyond

Dirk Schulze-Makuch suggests that a top predator in the oceans of Europa could be fearsome creature with mass of 1 gram. And the surface lakes of Titan could be home to hydrocarbon-guzzling microbes the size boulders.

But you'd have to go far beyond our solar system to find something you could actually talk to. What might it look like? Putting reasonable supposition together, says Stephen Battersby
the daring astrobiologist might be prepared to make a very small bet that SETI-type aliens will be social multicellular predators with eyes, sexes, and sticky-out bits of some sort.

P.S. 25 Jan Is there anybody out there?, asks the Royal Society.
