Dear Mónica,

This is an interesting puzzle. I am pretty sure it is the species I am calling Tambja sp. 6. It doesn't have a name and apart from its characteristic colour it has distinctly large oral tentacles more in keeping with the genus Roboastra. There are a few other species, such as T. tentaculata with similar oral tentacles.

Best wishes,
Bill Rudman

Dear Stacy,
This is another piece in the Tambja amakusana puzzle. Have a look at my comments about this species in an earlier message [#3545]. Your photo matches what I am calling Tambja sp. 6. but I think we have to consider whether that species, Tambja sp 9, Tambja sp.10 and Tambja cf. amakusana are all colour forms of one species which I guess would be T. amakusana.

Best wishes,
Bill Rudman

Tambja sp. 6? from Japan

September 19, 2002
From: Tomohiko Kurihara

Dear Bill.
Here are photos of an unknown opisthobranch. I found it at Osezaki, Suruga-bay, Japan. I found it on Bugula neritina in the daytime and when night comes,it was crawling on rock. I have ever seen this before. Is it a species of Tambja?

Dear Tomohiko,
This is an interesting find. From your mention of it on the bryozoan Bugula I am pretty sure it is a species of Tambja. I think it is the same as the species reported today by Dong Bum from Korea. It differs in having blue ridges on the mantle and blue spots on the sides of the body, but if you look at the Korean photos you can see the ridges on the mantle.
Best wishes,

Dear Bill,
Here are some photos of another Tambja sp. I have regarded it as Tambja amakusana. Could you give me some information about that?

Dear Dong Bum,
I haven't got any photos of typical Tambja amakusana to compare your animals with. Tambja cf. amakusana is possibly a colour form of T. amakusana but I think more animals need to be looked at to be sure. A number of these green species seem to have a yellow colour form but T. amakusana seems to have blue-tipped rhinophores, gills and tail while in your animal the blue seems to be much more extensive, including a blue median ridge from the posterior tip of the tail forward to join the posterior edge of the mantle edge. Until we know more I think it is best to call your animal Tambja sp. 6.
Best wishes,
Bill Rudman
