The first step of the process is fertilization. The barnacle will release sperm into the ocean through its penis. The sperm will travel until another barnacle consumes the sperm. When the sperm reaches another barnacle it is delivered to the mantle cavity to fertilize the eggs that are stored there. | The first step of the process is fertilization.

The eggs will hatch as a nauplius: small larval creatures with one eye, two antennae, and several mandibles. [http://webs.lander.edu/rsfox/invertebrates/balanus.html] The nauplius will usually molt six times before it morphs into the next stage. It usually moults once before it is released from the mantle cavity and into the open ocean. After it has spent its time as a free-swimming creature and has moulted enough it will change into its next form. | The eggs will hatch as a nauplius: small larval creatures with one eye, two antennae, and several mandibles.
