Dear Dr.Rudman,

Here are some photos of Hypselodoris sagamiensis. This is also very common in Sagami Bay and Echizen Coast.

These three photos were taken at the Echizen Coast, Japan, 11-12 August 2001. Upper right: 30mm, Lower right: 20mm, Lower left: 15mm.

Best Regards,
Nishina Masayoshi

Dear Nishina,
Thanks for these photos. I think I have only seen a couple of photos of H. sagamiensis before. This species is very interesting in having quite strongly developed pustules on the mantle, which is unusual in the family Chromodorididae. Another unusual feature is that no-one has found mantle glands in this species. In species of Hypselodoris the mantle glands are usually small sacs around the mantle edge, and in many species they become much larger and numerous around the posterior end of the mantle.

Best wishes,
Bill Rudman
