Concerning message #21055:
Dear Alexei and Bill,
I am in Japan right now to give a presentation this weekend on Stiliger berghi at the Japanese Malacological Society (Trowbridge, Hirano & Hirano). I just came across the Russian report of S. berghi -- what timing!
We have a ms on the species in The Veliger with SEM photos of the teeth. Under the light microscope, the teeth look non-denticulate but under SEM they are very clearly denticulate.
We have spent several years working on this species (Honshu and Hokkaido). I do not believe the species feeds on Neorhodomela but rather on Polysiphonia, Dasya, and Ceramium... such filamentous red algae may grow on Neorhodomela but the latter is not a sacoglossan food. (I have worked on Neorhodomela larix for many years in Oregon, its chemical ecology, grazers, etc.).
Beautiful photos! It is wonderful to see another Russian report of this species.
Cordially,
Cynthia
