Sensitive Sharks

Series 1, episode 0

Renowned wildlife expert David Attenborough looks at the finely tuned hunting skills of sharks. This incredible documentary reveals how their supercharged senses can pick up sound from over a mile away and detect electricity to five-billionths of a volt. Hammerhead sharks are now known to have an electrical sense to guide them across featureless oceans, while the Greenland shark - a monster from the frozen deep - is strangely blind.
