My Ferrolian friend, Richard, has kindly sent me this link to a short film about Galician fishermen harvesting percebes - or gooseneck barnacles - just outside the coastal town of Cedeira, half an hour north of Ferrol.

Richard and I politely disagree on the gastronomic qualities of these (indisputably ugly) things but I have no difficulty in agreeing with his suggestion that the activity is "probably more dangerous than catching fish in a force nine storm."

But it doesn't make them taste any better.
