Another black Chelidonura

Dear Bill
The attached Chelidonura OS0775, measuring 21 mm, was also found at the same time as the others in the same shallow sand flat area on the shores of Pulau Hoga in the Tukang Besi [Indonesia - Operation Wallacea] but I do not know whether it was part of a mating chain or not.

It was only on getting the film back that I noticed the blue area inside the mantle near the head. However the area of white near the sensory bristles is considerably narrower than in the other specimens.

Is this the same as the C. sandrana / tsurugensis ? ones?

All the best

Dear Lindsay,
I suspect this is a diferrent species. Sometimes the angle of the light will make some of these black ciliated surfaces appear bluish, but I think in this case there is a distinct pigmented blue line. I don't know of such a line in either C. sandrana or C. tsurugensis.

But if it is different, I don't think it is named.

Best wishes,
Bill Rudman.
