Unicorn Nembrotha chamberlaini

From: Marcel Tanke

Hi Bill,

In February 2008 in the Philippines, Puerto Galere, we saw this Nembrotha chamberlaini with only one rinophore. I suppose it was a birth defect, as it grew into a very large single rinophore; at least 2 cm.
Something for the Abnormalities page?

Locality: Philippines, 10-15 meter, Puerto Galere, 7 February 2008, reef. Length: 8 cm. Photographer: Marcel Tanke.

Best regards,
Marcel Tanke

Thanks Marcel,

I assume this green coloured animal is just a colour form of Nembrotha chamberlaini. In a couple of earlier messages you can see animals in which the reddish brown colour of the gills and their base is quite different from the brown saddle of the rest of the dorsum. This would suggest the 'saddle', which is green in your animals, is variable in colour while the gills and their base is not. You are right to compare your animal with unicorn - its single central rhinophore seems twice the size normally found in this species. I've added it to the abnormalities page.

Best wishes,
Bill Rudman
