#MARINE WILDLIFE - TED have posted video of the Irish Whale and Dolphin Group's Dr Simon Berrow giving a talk on the biggest fish in Ireland's waters, the mysterious basking shark.

The second largest fish in the world, basking sharks are almost extinct, and we know almost nothing about them.

But despite their huge size, we do know that they are among the friendlies of Ireland's marine wildlife.

Recorded at the TEDxDublin event at Dublin's Science Gallery in December 2010, the video above shows Dr Berrow describing the fascinating creature (known as the 'Great Fish of the Sun' in Irish) and the surprisingly low-tech methods he's employing in learning all he can to save them.
