Another odd one, Thorunna perhaps, from Moorea. Do you recognize it?

This is another example of the 'peculiar things happening in French Polynesia' which I have mentioned before. If you look at Thorunna australis you will see it has many similarities in colour pattern but there are obvious differences, in particular the colour of the gills and rhinophores. In these animals they are all orange but in typical T. australis both the gills and rhinophores have an orange band. I just find it strange that a number of widespread species with relatively stable colour patterns throughout their ranges, don't appear to occur in French Polynesia, but have a fairly close 'look alike'.
