DISTRIBUTION
Tropical Indo-West Pacific.

This species seems to be quite variable in colour, in particular, the head, rhinophores and oral tentacles appear to range in colour from a translucent orange to a dark translucent blue-black. The second point of variation concerns the areas with opaque white pigementation. In some animals the translucent body wall has scattered patches of opaque white while in other specimens there is a solid colouring of white.
