Deformed seaslug

May 29, 2009
From: Herbert Kramlofsky

Dear Dr Rudman,

I have got your homepage from Mr. Erwin Koehler, the German seaslug-pope. In November 2008 I was at the island Ambon (Indonesia, Molukku) for diving. When I was home again, I discovered on my video a seaslug with 2 gills, that means 2 openings in the body for the gills. I looked in a book for seaslugs (from Helmut Debelius). So I would say it's a Chromodoris sp.30. I made a picture from this videoscene. You will find it attached to this mail. Of course the quality of this photo is not as good as from a digitalphoto, but one can easy see the details.

Locality: Island Ambon, 8-10 metres, Indonesia, Indian Ocean, Banda Sea, November 2008, sandy bottom. Length: 50-60 mm. Photographer: Herbert Kramlofsky.

Have you ever seen a Chromodoris like this? If you are interested in this seaslug, I could send you this videoscene on DVD.
I am looking forward to your answer.
Respectfully
Herbert Kramlofsky

Dear Herbert,

I suspect your animal is Chromodoris lochi. Have a look at my earlier comments [message #22372]. I don't think I have seen an animal with two separate gill clusters like this. I wonder if this means it has two hearts - one for each set of gills? A paired abnormality like this suggest to me that this is the result of a developmental mistake when it was an embryo. It certainly hasn't stopped growing to a good size. It is certainly an addition to the Abnormalities page.

Best wishes,
Bill Rudman
