Imagine an alien with three hearts and ten arms growing out of its head. In an instant it could become invisible, or switch on the most electrifying light shows ever seen. This alien actually exists. The cuttlefish is one of the strangest animals on our planet. Leading expert Dr. Mark Norman reveals how these shape-shifting champions can hypnotize their prey, impersonate the other sex and even turn out to be deadly. And they share something with us: brainpower. Cuttlefish have the largest brain-to-body ratio of all invertebrates. But does this mean they are intelligent? Can they learn and remember complex new tricks? The documentary brings to the surface the spectacular pyrotechnics of these clever creatures, discovering just what goes on between their eyes and what they can teach us about our own wits.
