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?

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.
