Platydoris? or Discodoris? from Kerama Is.

November 14, 1999
From: Atsushi Ono

Dear Bill,
Thank you for quick reply.
This time, I am worried about some Doridacea species. They are from Kerama Is.[near OKINAWA in JAPAN].

UPPER PHOTO: I think this is Discodoris sp., probably 'Milne Bay Discodoris in NUDIBRANCHS OF THE SOUTH PACIFIC [ by Neville Coleman]. This individual is about 35mm long, at 5m depth. It has yellow margin and a few blurred light patchs on its body. This species is showed as Discodoris sp.5 in my book. This is only found night-diving, and is a rare species at Kerama Is.

LOWER PHOTOS: I think these are the same spceis as the one above. They are only found at night-diving, 20-30mm long, at 3-7m depth. This species is showed as Discodoris sp.2 in my book. They have a few little white spots on their body(some have no spot). This is common species here at summer season. I think this is similar to Platydoris sanguinea of your Sea Slug Forum on the Dorid Head page.

Is my species .
Could you help me identify for these species?

Dear Atsushi,
Sorry it has taken me a while to answer this enquiry. There are a number of similarly coloured species belonging to the genera Discodoris and Platydoris. I am pretty sure this is a Discodoris as species of Platydoris have distinctively raised edges to the gill and rhinophore pockets, which I can't see in your photos.

Does animal have a hard and rigid mantle. like in the animal you have called Platydoris formosa in your book, or is it softer like in Discodoris lilacina?

Best wishes,
Bill Rudman.
