Pollicipes cornucopia (Leach) is a common pedunculate barnacle found in rocky intertidal zones of the Atlantic coast of Spain. Embryos from the capitulum cavity of adults were incubated in the laboratory. Development throughout the seven larval stages (6 nauplius and 1 cypris) was studied in laboratory cultures. Descriptions and distinguishing characteristics are given for each larval stage. Morphological differences between this species and other intertidal barnacle larvae of the NW Spanish coast are discussed.
