Great white sharks live far longer than was previously thought.

Using a new technique to age the tissues of these impressive creatures, scientists have identified a male great white that lived into its 70s.

The researchers say the finding has important implications for the animals' protection.

The BBC's Rhod Sharp spoke to Li Ling Hamady, of MIT-WHOI in Massachusetts, US, about her study of longevity in great whites.
