Thorunna(?) species from Okinawa

April 13, 1998
From: Robert F. Bolland

Dear Bill:

The sea slug forum is a terrific idea and I'm very impressed with everything I've seen at the site.

Here is one of two .jpg files of separate Thorunna(?) species from here on Okinawa. I'm afraid that both of the photos are of very poor quality, but thought there might be enough here for at least a tentative identification(?).

Thorunna species #1 (TL: 11mm) was collected on 17 May, 1991 from Horseshoe Cliffs, Okinawa. The animal was found at 43m on a vertical rock wall covered with numerous corals, sponges, bryozoans, etc. Couldn't ascertain for sure what it was feeding upon. This is the only one I've seen here.

Cheers,
Bob

Looks very like Thorunna montrouzieri which is only known from specimens which I saw in northern New Caledonia in 1993. If your animal is indeed this species its quite an extension to its known distribution. There is also a photo in our photo gallery ....Bill Rudman.
