Arctic Cod or Polar Cod . To 60 cm ( 23.6 in ) TL ( Coad 1995 ). Circumpolar as far northward as 81°41’N ( Mecklenburg et al. 2011 ); two records off Alaska in Beaufort Sea, but north of US territorial waters (Mecklenburg et al. 2002); a carcass washed up on the Chukchi coast near Wainwright, Alaska ( Mecklenburg et al. 2014 ). Pelagic and probably also benthic ( Jordan et al. 2003 ), typically far offshore beyond continental shelf under drifting ice and in ice cracks (Cohen in Cohen et al. 1990 ), also in river mouths ( Jordan et al. 2003 ); depth: 0–930 m ( 3,051 ft (min.: Renaud in Coad and Reist; max.: Jordan et al. 2003 ). Molecular studies showed no genetic difference between A. glacialis and Arctogadus borisovi Dryagin, 1932 ( Møller et al. 2002 ), the so-called Toothed Cod. Jordan et al. (2003) examined morphology of both forms and revised the genus, classifying A. borisovi as a junior synonym of A. glacialis .
