Dear Bill,
Here is another of the nudibranchs that Charlotte and I found at Pemba Island, off the coast of Tanzania, western Indian Ocean, in November/December 2001.

Thanks Paul,
This is Chromodoris hamitoni which is, at present, known only from the western Indian Ocean. These two animals show an interesting colour variation which is not uncommon in this species. The orange can become quite reddish and parts of the black lines can become orange or brown. This colour variability seems to occur in similarly coloured species from the western Pacific, but we still need to understand the species limits better before we know if we are arguing in circles or not
Best wishes,
Bill Rudman
