Dear Bill,

In an earlier message [#21649]  you mentioned that this green coloured animal is a colour form of Nembrotha chamberlaini. I just want to bring to your attention that in the species list you refer to it as Nembrotha sp 9. Correct?

Locality: Puerto Galera, about 15 m, Philippines, 7 Februari 2008. Length: 10 cm. Photographer: Marcel Tanke.

In the Anilao and Puerto Galera areas of the Philippines these are quite common animals. In the N. chamberlaini Forum section, James McMahon's message [#21210] shows a similar colored animal. Attached is another one I have found.

Best regards,

Dear Marcel,

You are quite correct. Initially I separated off the greenish ones as these seemed quite different but as more photos accumulate the differences between the green and brown forms look less significant. When I get a moment I should amalgamate Nembrotha sp. 9 with N. chamberlaini

Best wishes,
Bill Rudman
