Re: First record of Polycera chilluna from S.Africa

Concerning message #19278:

Dear Bill,
I have included some more photos of Polycera chilluna. These are of the same individual taken on the same dive as the animal in the lower foto in my previous message [#19278]. These photos were taken on the wreck of the Aster in Hout Bay near Cape Town. The upper foto in the previous message was taken on the wreck of the Pietermaritzburg in False Bay. This will put them on both sides of the Cape Peninsula.

PS. You will notice a second nudibranch in the background of the lower photo. I will send it in a separate message [#19307 ].

Locality: Hout Bay, 20m, Cape Town, Atlantic Ocean, 11 February 2006, Wreck. Length: 5cm. Photographer: Wilhelm van Zyl.

Note added 9 February 2007: See photo of this form and P. capensis about to mate [message #19387] suggesting this is a colour form of P. capensis.

Dear Wilhelm,
These almost pure white animals certainly look different from most of the photos I have seen of P. chilluna and its European counterpart P. aurantiomarginata, but the thin orange lines and the subapical black band on the rhinophores certainly are the same. The yellow lining to the gills is not so obvious in your specimens but at least one gill [see inset] shows a yellow line extending down both edges. It is certainly an interesting find. Perhaps you should make a mental note to look out for fraternisation between this colour form and the black banded P. capensis.

Best wishes,
Bill Rudman
