Remarks
shark-references Species-ID=518; A separate species, the Bering skate (Bathyraja interrupta) resembles B. kincaidii and is common throughout the Bering Sea (Ebert 2003). These, and possibly other, Northeast/Eastern Central Pacific skates may represent a complex comprised of two to five different species within this range (D.A. Ebert unpubl. data). The systematics of this species is currently under investigation (D.A. Ebert pers. obs. 2007). This species has also been referred to as the Black Skate (Hart 1973, Gates and Frey 1974) or Bering Sea Skate (Ishihara and Ishiyama 1985) [18575]
