* Arctogadus glacialis (Peters, 1874),

often dated 1872 (Fricke et al. 2020). 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 .
