Unidentified Clionidae species in Toyama Bay.

We did pre Black Water Dive® at Namerikawa of Toyama Bay from 18th Mar to 20th Mar. Sea temperature was 10 degree. Visibility is not very well at that time, the results are were few. Most that we have found, it's common in the drifting plankton and nekton. However, there was a new discovery.
This is a very small Clionidae species. Size only 2mm. Cilia ring is three-stage.
So far, C, limacina limacina has not a report from Toyama Bay.
This species has also been reported from water sampling facilities of deep sea water of Toyama so far, and it has been found to be a new species.
