Hypelodoris obscura from Port Stephens
December 12, 2003
From: Leanne & David Atkinson
Dear Bill,
With the recent messages about Hypselodoris obscura we checked what you already had on the site and noticed there weren't any from the Port Stephens area. We get quite a few here in summer in the shallows. The duller colour variation is more common.
Here are some photos of Hypselodoris obscura mating. They were on the underside of an old piece of oyster rack that had obviously been unproductive for some time, by the amount of growth on it.
Photo details :
Date: 27 December 2002
Locality: Fly Point Marine Reserve, Port Stephens, NSW, Australia.
Depth: 9m Water Temperature: 19 Degrees C.
Tide: High 3:00pm 1.4m
Yours sincerely,
Leanne & David Atkinson

Atkinson, L. & D., 2003 (Dec 12) Hypelodoris obscura from Port Stephens. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/11645Thanks Leanne & David,
The mating apparatus is very blue in these animals. It is interesting that in some animals, the parts of the body that evert at times - parts of the reproductive apparatus and the oral tube - are distinctly coloured like this, while in other animals they are colourless. It seems to be an individual idiosyncracy rather than a character of a particular species
Best wishes
Bill Rudman
