Episode overview
Profile of the hammerhead shark, which has until now been shrouded in mystery as no-one could understand why its head is such a strange shape, or how it might help the creature's survival. Marine biologists in Hawaii explain how the fish utilises the unusual shape to give it a unique, deadly weapon in the oceans. Narrated by Ian Holm
