From: Tom Turk

Dear Bill,
Could you please comment on these two specimen of nudibranches. The picture was taken on the night dive in shallow water near the town of Selce in northern Adriatic. By my best knowledge it is the first picture of to me an unknown species which is probably very rare. This slugs were big, at least 15 cm.

Locality:  Selce, Croatia, Northern Adriatic Sea. Depth: 15 m. Length: 150 mm. few years ago. mixed sand and rocks. Photographer: Gianni Pecchiar. [Note added 19 April 2005: Length 50 mm NOT 150 mm [see #13569]]

Dear Tom,
Thanks to you and Gianni for this beautiful photo of Gastropteron rubrum swimming. This species ranges in colour from this dull reddish brown to a bright red. There is a photo on the Forum of a red specimen from the Adriatic Sea [#9020 ].

Could you possibly confirm the length of 150 mm? This seems very large. I would be surprised if it grew longer than 35 - 40 mm.

Best wishes,
Bill Rudman
