Siphopteron sp. 5 from Botany Bay

January 16, 2004
From: Bill Rudman


After posting Nils Anthes' message of the very variably coloured Siphopteron sp. 5,, I realised I had a record of what is almost certainly the same species from Sydney, New South Wales, certainly a lot further south than Nils' record from the Great Barrier Reef.

• Quibray Bay, Botany Bay, Sydney, New South Wales, Australia. On Sargassum, 27 June 1981. Coll: B. Brandley. 3 animals - 6,4,5mm long alive. AM C130162. Photo: Bill Rudman


The parapodia & visceral hump is dark brown with scattered white or translucent clear patches. The edge of the parapodia have many opaque white patches. The headshield is translucent greyish with some brown patching & mottling. The gills are black.
In the photographed specimen the parapodia have distinctly reddish brown patches. There are a pair of short white triangular papillae on the posterior edge of visceral hump. They can swim when disturbed.

Best wishes
