English barnacle; origin disputed. Often compared to a Celtic root (compare Breton bernik, limpet), but the word is first recorded for the barnacle goose, with the shellfish sense following later, so a single clean derivation is not established
Common acorn barnacle, a sessile filter-feeding crustacean enclosed in conical calcareous plates cemented to rock. Abundant on North Atlantic intertidal shores.
