Aliens of the Deep Sea

It has a soft boneless body and two eyes that take up a quarter of its body weight. It has eight tentacles of which one contains the sex organ, brain and intestines all in a single pouch. It’s a carnivorous predator with a tearing beak that can grow up to five metres long! It can change shape and colour at will, disappearing into the background, with a formidable intelligence able to solve complex problems and the ability to walk on land, sea and cross through fire. It’s not an alien from outer-space but an Octopus, a creature that has lived alongside humankind from the beginning. In a one-off special, Aliens of the Deep explores how we are only beginning to unravel the extent of the astounding intelligence of this strange but fascinating deep water wonder.
