Shima Pref. Mie, Japan (Kii Peninsula), Depth: 2-3m, Length: 4-10mm, Jan - Feb. 2000. PHOTO: Yasuhiro Shirai.

Originally described from a single 4mm long specimen [Etizen Coast, Japan Sea side of Honshu Id]. The dorsal hump and outer surfaces of the parapodia were deep choclate brown and their were irregular white markings, towards the margin in the case of the paraoodia. The tip of the siphon and the edge of foot and parapodia were described as deep vermillion. I don't think there is much doubt that the animal photographed here is S. fuscum.
