Notochthamalus scabrosus (Darwin, 1854) is commonly attached to littoral rocks and shells, often associated with Notobalanus flosculus (Darwin, 1854), and sometimes with Chthamalus cirratus (Darwin, 1851). Notochthamalus scabrosus was previously reported from Perú to Tierra del Fuego and Islas Malvinas / Falkland Islands by Darwin (1851). Moreover, the review of South American barnacle distribution by Young (1995) suggested that the températe zone of the Southwestern Atlantic, occurring between 35°S and the southern tip of South America (56°S), had a barnacle fauna similar to that of the Southeastern Pacific (coasts of Chile and Perú), with N. scabrosus occurring at both zones. Particularly in the Beagle Channel, N. scabrous is the dominant species in the upper zone of the rocky intertidal.
