Hi jeltje...

Yes some of these larger slugs can be problematic to get a positive id from, especially from photos. I can't be 100% but yours will probably be Arion ater?

Not all of these slugs will need to be dissected, there may be a few characteristics shown on various specimens that will allow you an id without dissection.

You may be interested in the new up and coming book that should be hitting the shelves keep an eye for it. :)

I have only been to the UK twice (2 weeks in 2011 and 10 days in 2013),but I'll check out the slug book if I come on holiday in the future.
