Distribution South Orkney Islands; South Shetland Islands; Palmer Archipelago; 0–15 m (De Broyer et al. 2007). Epimeria monodon was recorded from rocky intertidal communities (Aghmich et al. 2016) and was found amidst macro-algae (Richardson 1977). Thurston (1972) stated: “apparently associated with algae growing on rocks, boulder or gravel bottoms, 3–15 m ”. Remarks The record of E. monodon from the eastern shelf of the Weddell Sea at 254 m listed in the data compilation of De Broyer et al. (2007) falls outside of the usual geographical and bathymetric range of the species. It is considered as very suspect. It might be based on E. annabellae, which is common at such depth in the eastern Weddell Sea. It seems possible that E. monodon, which is a very shallow-water species, uses algal rafting as a method of dispersal between islands and archipelagoes. Thurston (1972) recorded a slight ...
