Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Southern Ocean: islands of the Scotia Sea, Weddell Sea, Prydz Bay and the Ross Sea. A separate subspecies may be present in the Ross Sea population, but this needs more evidence (Ref. 5179). Reported from Olaf Prydz Bay, Mackenzie Sea, Indian sector of the Antarctic (Ref. 44178).

Biology     Glossary (e.g. epibenthic)

Feeds on zooplankton. The storage of lipids in cells of adipose tissue as well as the reduced calcification of the skeleton provide buoyancy to this species.
