Egg production in three orders, Acrothoracica, Rhizocephala, and Thoracica has been dealt with in this review. The Acrothoracica are burrowing forms, the Rhizocephala are parasitic, and the Thoracica the true barnacles. Much of the information on egg production concerns the Thoracica. There are, however, scattered references to egg production in the other two orders. Cirripedes may be hermaphroditic or have separate sexes in which case dwarf males are needed for fertilisation. Eggs are developed outside the body but within the mantle cavity of the adult. The relative virtues of self- and cross-fertilisation have been discussed.
