Editing Barnacle (section)

=== Adult ===

Typical [[acorn barnacle]]s develop six hard calcareous plates to surround and protect their bodies. For the rest of their lives, they are cemented to the substrate, using their feathery legs (cirri) to capture plankton. Once metamorphosis is over and they have reached their adult form, barnacles continue to grow by adding new material to their heavily calcified plates. These plates are not [[ecdysis|moulted]]; however, like all [[ecdysozoa]]ns, the barnacle moults its [[Cuticle#Invertebrate zoology|cuticle]].<ref>{{cite book |author=E.
