With its three hearts, blue blood and boneless body, the octopus is the closest we may get to meeting an alien. They evolved from a common cousin more than 500 million years ago. But they’re also intelligent creatures, with proven problem-solving abilities. So what happens when you invite an eight-legged alien into your living room? This film follows marine biologist David Scheel as he tracks his complex, evolving relationship with his own octopus. Using David’s first-person narrative and linking his discoveries to octopus stories from all over the world, the film offers an insight into the extraordinary intelligence and behaviour of these incredible creatures.
