distribution
Distribution South Orkney Islands; South Shetland Islands; Antarctic Peninsula; eastern shelf of the Weddell Sea; Davis Sea; Adélie Coast, Ross Sea; 0 – 1200 m (Coleman 2007; present data). As many records of E. macronyx come from pelagic nets (De Broyer et al. 2007; present data), and as the species is very slender with large eyes reminiscent to those of hyperiids, it is obviously a true pelagic species.
