In the first Living World of the autumn run, Chris Sperring travels to Exeter to find a species hidden within the walls of Exeter Cathedral. First found at the Cathedral as far back as 1890, the large tube-web spider or Segestria florentina, is the largest European spider from the Segestriidae family and one of the largest spiders found in the UK. Chris Sperring and Peter Smithers, Professor at the School of Biological Sciences at Plymouth University, go on a quest (with a surprising array of props) to find the species concealed amongst the Cathedral's gothic architecture.
