Noumea margaretae? from New South Wales

February 26, 2001
From: Judith Martin

The attached photo was taken at Fly Point, Nelson Bay, New South Wales [Australia] around Christmas. Viz was around 10 meters, water temp around 20c. Depth was 15 meters. This nudi was crawling along the sand and shell grit bottom.The nudi first looked like a Chromodoris daphne, but it's gills and rhinophores are white.
Thank You

Dear Judith,
C. daphne also has both a red and yellow border to the mantle. If you look carefully at the rhinophores in your photo you will see a red spot about midway down the front edge. This is typical of Noumea haliclona and separates it from all the other red-spotted chromodorids in southeastern Australia.

You will see at the top of this page that this species has quite distinct colour variations in different parts of southeastern Australia. In all cases the red spot on the rhinophores is present. Noumea margaretae is a name previously given to the pink colour form from Victoria.
Best wishes,
Bill Rudman
