What else is out there? Spider 'extinct' for a century found in Dorset
It is a find that has stunned wildlife experts. A tiny spider thought to have been extinct in Britain for more than a hundred years has been found on a nature reserve in Dorset.
Small as it, it has a big name - hypsosinga heri - and it was last seen in East Anglia in 1912.
Our environment correspondent Duncan Sleightholme went in search of it.
