Dear Bill,
Melanochlamys diomedea is one of two aglajid species in north-west part of Sea of Japan. The second species is Philinopsis gigliolii. M. diomedea is common in the Japan Sea from Peter the Great Bay to Tatar Strait and South Sakhalin. It lives in sand at depths 0-80 m (Chaban, Martynov, 1998). The body is a black mottling, but the some specimens show very dark uniform coloration (Photo by A. Ratnikov)

Locality:  Peter the Great Bay, Russia, Sea of Japan, Pacific Ocean. Depth: 8 m. Length: 9 mm. August 2003. sand. Photographer: A.V. Ratnikov.

  • Chaban E., M., Martynov A. V. (1998)  Melanochlamys diomedea (Bergh, 1893) (Opisthobranchia: Aglajidae), a new genus and species in the fauna of Russia. Ruthenica, 8(2): 147-152 (in Russian).

Dear Alexei, Elena & Alexander,
This is another interesting range extension. It would be nice to get some photos from the Nth American coast. Have you any thoughts on Melanochlamys ezoensis which Baba described from northern Japan. Unfortunately I don't know anything about it except its external appearance, but it seems to me it could just be a mottled form of M. diomedea.
Best wishes,
Bill Rudman
