Seas of Japan and Okhotsk, Commander, and Aleutian Islands, Gulf of Alaska to Strait of Juan de Fuca, and northward to Chukchi and Beaufort Seas eastwards to at least Davis Strait, and southern end of Baffin Island, eastern Canada . Presence in Siberian Seas unclear ( Mecklenburg et al. 2016 ). Pelagic, nearshore; marine and brackish waters ( Dyldin and Orlov 2017 ); depth: intertidal to 575 m ( 1,886 ft ) (min.: Mecklenburg et al. 2016 ; max.: Kim and Kim 2019 ). Until recently believed to be a junior synonym of Mallotus villosus (Müller, 1776) . However, molecular genetic studies demonstrate a substantial genetic distance between this species and other Arctic Mallotus spp. clades ( Mecklenburg and Steinke 2015 ).
