A delightful little story at the Guardian about an Italian snail that stowed away on imported Victorian stonework (via paperpools):

The snail, Papillifera bidens, was thought to have arrived on a balustrade from the Villa Borghese in Rome in 1896, and with suitably snail-paced progress seems to have taken more than a hundred years to reach stonework 60 yards away.
