Could this be Discodoris lilacina

January 11, 2007
From: Dennis Hutson

Hi Bill,
I found this little creature on a recent dive. The location was just out from the boat ramp of our shipping channel leading into the Port River. This area is known as Outer Harbour. Local waters of Gulf St. Vincent, South Australia. I photographed this nudibranch and after consulting Neville Coleman's book "1001 Nudibranchs", I thought it might be Discodoris lilacina. I am only able to go by basic visual characteristics. Is this critter local to my waters?

Locality: Outer Harbour, Adelaide. Depth: 4 metres. South Australia. Length: 40 mm. 20 August 2005. Silty bottom. Photographer: Dennis Hutson

Thanks for your continued support.
Cheers
D.

Dear Dennis,

I am too embarassed to say how long this message has been waiting from me to prepare a Fact Sheet on Paradoris dubia. My apologies. Your animal looks like a Discodoris, and in fact has been placed in that genus until Benoit Dayrat's recent revision of the genus Paradoris. As you may have guessed by now, your animal is Paradoris dubia. It usually has ring-shaped marks on the mantle which are quite distinctive. I have posted a Fact Sheet today. Have a look at that and the accompanying messages I am also posting to show colour variability.

Best wishes,
Bill Rudman
