Some barnacles are considered edible by humans, including Japanese goose barnacles ("e.g." "Capitulum mitella"), and goose barnacles ("e.g." "Pollicipes pollicipes"), a delicacy in Spain and Portugal. The resemblance of this barnacle's fleshy stalk to a goose's neck gave rise, in ancient times, to the notion that geese literally grew from the barnacle. Indeed, the word "barnacle" originally referred to a species of goose, the barnacle goose "Branta leucopsis", whose eggs and young were rarely seen by humans because it breeds in the remote Arctic.
