CIRRIPEDE

any of the marine crustaceans of the subclass Cirripedia (class Maxillopoda). The best known are the barnacles. Adults of cirripedes other than barnacles are internal parasites of marine invertebrates such as crabs, jellyfish, and starfish and have no popular name. Additional reading Charles Darwin, A Monograph on the Subclass Cirripedia, 2 vol. (185154, reissued as vol. 1113 of The Works of Charles Darwin, 1988), is a comprehensive monograph on the Thoracica and still an important source. Paul Krger, Cirripedia, in Bronns Klassen und Ordnungen des Teirreichs, vol. 5, div. 1, fasc. 3, pt. 3 (1940), pp. 1560, provides an authoritative compilation of knowledge. Alan J. Southward (ed.), Barnacle Biology (1987), includes chapters on evolution and genetics, physiology and function, larval biology and settlement, and pollution and fouling. H.G. Stubbings, Balanus Balanoides (1975), is a comprehensive monograph on the best-known barnacle in the world. Useful journal articles include D.T. Anderson, The Larval Musculature of the Barnacle Ibla quadrivalvis Cuvier (Cirripedia, Lepadomorpha), Proceedings of the Royal Society of London, Series B, 231(1264):313338 (1987), an in-depth comparison of the larval musculature of one of the most primitive pedunculate barnacles with that of a rhizocephalan and balanomorphan; and W. Klepal, Ibla cumingi (Crustacea Cirripedia): A Gonochoristic Species (Anatomy, Dwarfing, and Systematic Implications), Marine Ecology, 6(1):47119 (1985), a study of the gross and fine structure.
