Polycera aurantiomarginata from Senegal

March 27, 2003
From: Marina Poddubetskaia


Dear Bill,
Some time ago Patrice Petit de Voize showed me his photos from Dakar, Senegal. Each year he organizes a course on Senegalese fauna there.

I was very glad to discover these photos he had of Polycera. I think this is Polycera aurantiomarginata. So, I really wanted to share this discovery with you, and Patrice said to be happy to contribute to the Forum. He has many photos of this species, so I think it is quite common there. I will send in a separate message photos of mating and spawning. But I didn’t see any obvious feeding behaviour.

So, all the photos were taken by Patrice Petit de Voize [PdeVoize@aol.com] in Dakar on the Tacoma wreck in April 2001. The water was cold, 15-17°C and the depth was from 6 to 12m.

Best wishes,
Marina (and Patrice).

Dear Marian & Patrice,
This is indeed an exciting find, for as far as I know Polycera aurantiomarginata has only been reported from Spanish waters, and then only rarely. The orange-yellow border to the foot, and the blue-black rhinophore club with yellow tip, are both characters unique to this species. There is clearly still a lot for us to learn about the fauna of the west African coast. Any other of Patrice's photos from west Africa are of course very welcome, even of species common elsewhere, as we know so little about the fauna of that region.
Best wishes,
Bill Rudman
