Locality: Coolangata area, 50-100 mm, New South Wales, Australia, Pacific Ocean, 28 July 2007, Intertidal muddy creek. Length: 35-43 mm. Photographer: Gary Cobb.

Cheers

Thanks Gary,
It is a spectacular animal. I have included a grey version of the open parapodia because I think it shows the arrangement of the branching blood vessels more clearly than in the colour version. The arrangement of these vessels has been used by some authors to differentiate species.

If the egg ribbons are plentiful it might be intersting to scrape away the silt to see what the eggs look like - both colour and size, and whether they have extra-capsular yoke.

Best wishes,
Bill Rudman
