description
Broadbanded Thornyhead or Broadfin Thornyhead. To 41 cm (16.1 in) TL (Poltev 2011). Seas of Japan and Okhotsk to Commander Islands (Mecklenburg et al. 2002), Pacific Ocean south of Aleutian Islands (eastward to 54 ° 22 ’ N, 166 ° 21 ’ W) (Maslenikov et al. 2013), and Bering Sea south of Cape Navarin to eastern Bering Sea (Mecklenburg et al. 2002). Benthic; depth: 100 – 1,504 m (328 – 4,934 ft) (min.: Orlov and Kochkin 1995; max.: Mecklenburg et al. 2002). Many of the earlier records for this species in the eastern Bering Sea pertain to S. alascanus. The vernacular “ broadbanded thornyhead ” may have originated as a typographical error for broadhanded (translation of macrochir), in reference to the pectoral fins (Mecklenburg et al. 2002); the fish does not have any bands of color. The AFS – ASIH list of North American fish names (Nelson et al. 2004) now gives the name Broadfin Thornyhead for this species.
