If Aliens really are amongst us, the most likely candidates may not be little green men, but living in plain sight, just below our ocean waves, in the form of the mysterious and awe-inspiringly clever Octopus. Scientists are only just discovering the amazing intelligence of these elegant and highly unusual creatures that seem to have evolved in a completely different way to nearly any other creature on the planet. Brian and Robin are joined by marine biologist Dr Tim Lamont, Neuroscientist Dr Amy Courtney and comedian Russell Kane to uncover just how clever these mysterious creatures are, how they've evolved intelligence in an entirely unique way and whether 8 brains, as well as 8 legs are really better than 1. The panel also discover the alarming truth about the unique sex lives of the octopus - lets just say it doesn't end well for at least one of the participants.
