Syphonota geographica from Dominica

July 23, 2004
From: Linda Ianniello


Dr. Bill,
Here are two shots of Syphonota geographica that I recently found in the Caribbean.

Location: Dominica, Eastern Caribbean
Sea grass bed off Castle Comfort Hotel
Depth: 20 to 25 feet
Date: July, 2004
Size: approximately 4 inches

We saw several of them each night, but none during the day. They were crawling in the sand around the sea grass, but I didn't see any evidence of what they were actually feeding on. One shot shows two together, with eggs. I hope this helps prove it is 'circumtropical' and extends its reported range!

I really miss looking at your updates to the Forum every day, but am very glad to see that you are finding the time to add a few items each week. I'm sure it is taking away from your free time, but the Forum is such a great resource that we do appreciate your efforts
Regards,
Linda I.

Dear Linda,
This is indeed an interesting find. It is not mentioned in Eveline Marcus's review of the western Atlantic Anaspidea (1972) and I certainly could not find any early records of this species from the Caribbean when I looked some time ago. So as you say this is a new find for the Caribbean and does indeed give the species a circumtropical distribution. The question that must be considered is whether this is a recent arrival, as I suggested from Mediterranean records on the Forum [#8637], or is it a species which has been overlooked in the past?

• Marcus, Ev. (1972) On the Anaspidea (Gastropoda: Opisthobranchia) of the warm waters of the western Atlantic. Bulletin of Marine Science, 22(4): 841-874.

Concerning the Forum. Hopefully I can aim at a few messages daily. Your message again illustrates just how shortsighted are those that hold that the Forum is not a valuable source of new scientific information.
Best wishes
Bill Rudman
