Type locality.

Aburatsubo Bay, Miura, Japan.

Distribution.

South Japan, South Korea, Korea (East China Sea), and China (Yellow Sea), at 1-50 m depth.

Remarks.

There are some detailed descriptions about this species (e.g., Nakamoto 1923; Carlgren 1924). Uchida (1979) described the color variation of specimens from Japan (Kushimoto) and some ecological aspects. The same author also compared C. filiformis to other specimens described from the same area and concluded that all specimens belonged to the same species. This assumption includes the specimen from Okinose Bank, Sagami Bay (Kanagawa, Japan) described by Wassilieff as C. orientalis Verril, 1865. This specimen is deposited in the Zoologische Staatssammlung München (ZSM; 173/D65) and does not belong to the genus Cerianthus but to Ceriantheomorphe (S. Stampar pers. obs.). It is not very well preserved, but the overall organization of the mesenteries is quite consistent with that of Ceriantheomorphe ambonensis (Kwietniewski, 1898). The occurrence of Ceriantheomorphe in Japanese waters was also discussed by Molodtsova (2001b).
