Bornella from South Africa

November 7, 1999
From: Valda Fraser

Dear Bill,
Can you help me identify orange and white dendronotid? please.

It is from the south Coast of Kwa Zulu Natal, South Africa, near Port Shepstone. Low and high profile rocky reef, 25 - 45m, July 1999. It was 70mm long.

Kind regards,
Valda Fraser

Dear Valda,
You are right in thinking it was a member of the Dendronotoidea. It is, I think, a species of Bornella. I have seen photos of this before and thought it might be a large form of the relatively common Bornella stellifer but your photo is much clearer, and from the distinct colour pattern and arrangement of the cerata, I suspect it is quite different. Each cluster of cerata seems to have a common base which is quite unusual for Bornella. have you any other photos of this animal? It would be good to see the head more clearly.
Bill Rudman.
