Distribution and habitat This species is found along the coasts of Brazil and Uruguay, mostly in the mid-intertidal zone. It is the most common limpet with large population sizes in the Brazilian midlittoral. It can fill the small gaps in mussel beds dominated by Brachidontes solisianus and Brachidontes darwinianus. They are also very abundant in the regions dominated by the barnacle Tetraclita stalactifera.
Description The shell size is between 16 and 30 mm
