Observations on the intertidal barnacles (Cirripedia: Balanomorpha) at Fossil Island, Tasman Peninsula: physical tolerances, orientation and fertilisation

摘要

Six species of barnacle are found intertidally at Fossil Island. Tolerances of the species touddesiccation and temperature could be related to their position on the shore. The four commonudspecies all show significant orientation to water currents: in Catornerus polyrnerus the orientationudis reversed lower on the shore. Strong evidence is presented that isolated C. polyrnerus individualsudcan self-fertilise.
