Last weekend our DEPC (Digital Eco-Photo Club) members visited the Yellow Sea.
We've got several photos from Tae An area.[126° E 36° 8'N] including this one of Noumea nivalis.

Thanks for the photo. I guess this was a reasonably small animal. Certainly the mantle glands look like those of a juvenile. I wouldn't be surprised if it is an unnamed species. From my experience of similarly coloured species in southeastern Australia, colour patterns and actual colours can be very stable. It is possible that yellow spots like this, rather than orange, are an indication that it is not N. nivalis. Also the yellow spots at the mantle edge are rather different from the continuous orange band found in N. nivalis.
However, the only way to be sure would be to look at its anatomy.
