Observations on the intertidal barnacles (Cirripedia: Balanomorpha) at Fossil Island, Tasman Peninsula: physical tolerances, orientation and fertilisation
Six species of barnacle are found intertidally at Fossil Island. Tolerances of the species to desiccation and temperature could be related to their position on the shore. The four common species all show significant orientation to water currents: in Catornerus polyrnerus the orientation is reversed lower on the shore. Strong evidence is presented that isolated C. polyrnerus individuals can self-fertilise
