From the Independent comes a story about an alien species of snail that have overrun part of England. Well, a very small part of England. The snails, called the Cliveden snails after the stately home where they were discovered apparently were introduced: "from an imported stone balustrade brought from Italy in the 1890s, to claim a piece of British territory up to the terrace of the house just 27m (88ft) away."
So no need to panic.
