Chromodoris lineolata? from Japan

May 15, 2003
From: Toshihiro Horiuchi


Dear Bill,
I found this chromodorid at Amami Ohshima Island, Kogoshima, Japan. I found it in shallow water at Kurasaki Beach on rock.

I think that probably it is C. lineolata, but it may be C. striatella. Could you help me to identify this?

Date: March 2003
Water temperature: 19 degrees
Depth: 5m
Size: about 15mm.

Best regards,
Toshihiro Horiuchi

Dear Toshihiro,
I agree that this is most probably C. lineolata rather than C. striatella. C. lineolata and C. striatella can usually be easily differentiated by the colour directly inside the orange mantle margin, - black in C. lineolata and translucent white in C. striatella. However in your animal there is a very noticeable pattern of 5 blackish patches between the gills and the rhinophores which is very characteristic of C. striatella. We may discover that the two are just forms of one species, but at present I would call your animal C. lineolata.
Best wishes,
Bill Rudman
