Lobiger from Heron Island mating

April 25, 2005
From: Julie Marshall


Dear Bill,

Attached are two photos of Lobiger souverbii mating - or attempting to mate - it is almost impossible to tell where one animal ends and the other begins! Bob Burn found 9 specimens of this species on Caulerpa racemosa whilst sieving the algae on the reef flat at Heron Island [Great Barrier Reef] at low tide last month. Interestingly all of them lacked the blue lines on the mantle, although I have found animals with blue lines on the mantle in the past at Heron Island.

Locality: Heron Island, Great Barrier Reef. Depth: Intertidal. Length: 14 mm. 18 March 2005. Photographer: Julie Marshall

Best wishes,

Thanks Julie,
It certainly is a bit hard to separate the two animals. Concerning the name Lobiger souverbii. As you will see in earlier discussions it really depends if there is one circumglobal species or not as L. souverbii was first applied to a Caribbean animal. I am continuing to use Lobiger viridis for Indo-West Pacific animals at present. I suspect we will need some DNA studies to be sure
Best wishes,
Bill Rudman
