Lycodes mucosus Richardson, 1855 .

Saddled Eelpout or Lightcheek Eelpout. To 49 cm (19.3 in) TL (Andriashev 1954); at 48.5 cm SL, a specimen in the University of Washington, Burke Museum of Natural History and Culture Fish Collection (UW 111520) was probably a bit more than 49 cm TL but the caudal rays are broken off (Catherine W. Mecklenburg, unpubl. data). Chukchi Sea eastward to Cumberland Sound, Baffin Island, and north-western Greenland; southward to Bering Sea to Gulf of Anadyr, and south side of Saint Matthew Island (Mecklenburg et al. 2016). Benthic; depth: intertidal to 184 m (590 ft) (Mecklenburg et al. 2016). Note that in the past this species, Lycodes turneri, and Lycodes polaris have often been mistaken for one another. Lycodes knipowitschi Popov, 1931, a Sea of Okhotsk endemic, may be a synonym (Mecklenburg et al. 2016).
