Geographical distribution. ANTARCTICA: Antarctic Peninsula. SUBANTARCTICA: -. SCOTIA ARC: South Orkney Islands, South Shetland Islands. SOUTH AMERICA: -. Remarks. We found it at several stations between the intertidal zone and 100 m depth. Margarella antarctica is associated to spots with macroalgae and rocks. The species is already known from Maxwell and Admiralty Bays. It seems to be quite common in the waters around King George Island (see also Engl 2012). References. Arnaud et al.
