Ecology and distribution. Species found, in Antarctic waters, at depths between 12 (Stepanjants 1979) and 1157 m (Peña Cantero 2014a); present material from 85 to 451 m, epilithic on gravel and epibiotic on Billardia subrufa, Campanularia hicksoni, Staurotheca densa, S. nonscripta and tube of benthic organism. Cosmopolitan distribution, frequently reported around Antarctica. Recently reported from off Livingston Island (Peña Cantero 2006, 2008), Bouvet Island (Peña Cantero & Gili ...
