Chromodoris cf. colemani from Malaysia

June 27, 2001
From: Aw Seng Meng

Dear Dr. Rudman,

Could you please ID this nudibranch; it may be just a colour variant of a common Chromodoris but I cannot find any similiar picture in my books.

This branch was photographed last month on Kapas Island, an island off the East Coast of Peninsular Malaysia. It was about 2.5cm long, in 8 metres of water in the afternoon, on broken hard coral.

Thank you.

Dear Meng,
I think this is probably an orange form of Chromodoris colemani. At the moment I am storng a group of puzzling animals with orange in their colour patterns on this Chromodoris cf. colemani page. I suspect they are not all the same species but they are easier to find here than if I numbered them individually as unknown species. As you will see a number come from Malaysia and nearby waters. There are some interesting 'species' or apparent 'color forms' of more widespread species, appearing from Thailand and Malaysia, so any other intersting photos you would like to share with us would be very welcome. They would help build up our knowledge of the distribution and colour variation of these intersting animals.
Best wishes,
Bill Rudman
