Habitat In Robert Island (South Shetland Islands), the species was collected from a rocky shore during low tide, in the lower intertidal fringe, amongst the alga Gigartina skottsbergii Setchell & Gardner, 1936. In Doumer Island (Palmer Archipelago), the species was collected from the intertidal down to 30 m deep in the subtidal seabed zone, reaching the highest densities between 12 and 20 m depth, which corresponds to a zone dominated by species of the red algal genera Iridaea, Plocamium, Ptilonia, and Callophyllis. [details]
Reproduction A female 21 mm long, for 41 setigers, was collected with a mucous egg cocoon in the lower intertidal fringe of Robert Island attached by mucous to Gigartina skottsbergii. The mucous egg cocoon preserved in alcohol measured 3 mm in diameter and contained at least two layers of eggs, with the outer layer having 143 dark brown eggs, 261-360 µm in diameter. [details]
Type locality South Bay, Doumer Island, Palmer Archipelago, Antarctica (-64.8667º, -63.6º), at 12 m, on the seabed. [details]
