Notes on SEM study of cirriped Chthamalus challengeri larvae

Light microscope examination of the metamorphosing larvae of barnacles has been found to be inadequate to describe their characters of taxonomic value . The use of scanning electron microscope (SEM) is therefore suggested by s ome workers. The larvae of Chthamalus challengeri Hoek were examined under SEM to describe the setae and setulation of the appendages. The technique h as merit to remove some of the discrepancies in larval descriptions of barn acles reported in the literature from time to time.
