According Bill Rudman " I think the colour differences in the gills and rhinophores that you mention are of great importance, but we don't know enough about juvenile colour patterns to know whether the absence of the black marks on the rhinophore stalks and the black colour on the gills is a result of the small size of this animal.[....] It looks like there is the start of a black line of the right rhinophore stalk which would suggest it may be a juvenile still developing its colour pattern."
