Where do we look for intelligence?
In this ground-breaking documentary, we look at how the idea that ocean animals can think, feel and be conscious is increasingly becoming accepted by researchers and the broader public.
This concept is for most of us almost as difficult to accept as the concept of an infinite universe.
When we dive beneath the surface we find animals that are capable of cooperation, have their own languages and can think in the abstract. And the deeper we dive the more remarkable the discoveries.
