Look what Mrs C found in the bathroom today! A very large woodlouse spider – at least 25mm including legs, which seems to be as large as they come. I've seen smaller ones before, about half this size. Yes, this picture was taken through the side of the pint glass that I put over it! These slightly scary spiders have very large bitey things at the front (technical term chelicerae) and can give a nasty nip apparently, though are unlikely to.
