Re: Sea Slug from the Red Sea

March 6, 2003
From: Mark Burnett

Hi Bill,
Not sure if this is relevant but when I read Aline Flemming's message earlier today I was reminded of a picture I took in the Red Sea way back in April 1994. At the time I thought it was a nudibranch but soon found I was mistaken. I have since found many flatworms that could be mistaken for nudibranchs from their colours but obviously they lack gills and rhinophores. This picture is of Pseudoceros cf. dimidiatus as identified on Wolfgang Seifaith's Marine Flatworms of the World site. It was taken at Al Nakheel, a resort just north of Jeddah, Saudi Arabia. The only thing that puzzles me is the mention of eyes, otherwise the colours fit Aline's description. It looks like Reticulidia halgerda.

Dear Mark,
I think this is an excellent solution to the puzzle. I agree the eyes are a bit of a puzzle - but they are not easily seen in most nudibranchs either - so it is possible Aline is describing a couple of black spots.
Best wishes,
Bill Rudman
