This story is a couple of weeks old now but I’ve found a link for some TV footage so take a look. It’s a new type of slug previously unknown to science and lives soley on earth worms. Although the news presenter in the video suggests there is nothing to worry about with this slug I wouldn’t want them in my garden killing off earth worms, which of course are massively beneficial. It is thought to have been imported to Britain by mistake from another country, just like that other worm killer the flatworm. It’s a welsh slug so its been given a Welsh latin name Selenochlamys ysbryda. Ysbryda is Welsh for ghost. The library computer wont let me make a link so I’m afraid its a cut and paste job. http://news.bbc.co.uk/1/hi/wales/south_east/7498195.stm
