''Balanus balanus'' is a species of acorn barnacle in the Balanidae family. It is native to the colder seas of the northern hemisphere. ==Description== Unlike most crustaceans, barnacles are unable to move from place to place. Cement glands near the base of the antennae fix them to the rock. The carapace of this species is conical with a circular base which has an irregular edge and a diameter of up to three centimetres. The surface is ridged and white or pale brown. The cover plates protecting the opening are shaped like the beak of a bird.
