Elysia from Japan

March 13, 2000
From: Yasuhiro Shirai


Dear Bill,
I attached 2 image files. I think the upper one is juvenile (5mm long) and the lower one is adult (20-30mm long).

Their body color is brown and they have white tip on their side. I think they are Elysia sp.

Could you please identify it for me?

Data:
Location: Shima Pref. Mie, Japan (Kii Peninsula, east coast)
Length: 5mm(juvenile), 25mm(adult).
Water temperature: 15C
Date Feb.2000
Depth: 2m Crawling on seaweed.

Best regards,
Yasuhiro Shirai

Dear Yasuhiro,
I do not recognise this species. It is probably a sacoglossan but it also looks quite like the dendronotoid Crosslandia viridis. If you have an enlarged photo of the head I would like to look at the rhinophores to see if they are sacoglossan-like or like a dendronotoid.
Best wishes,
Bill Rudman.
