Chromodoris sp. 12 (Undescribed)

This chromodorid nudibranch has some of the most complicated coloration of all the other species in this genus.

It's notum is cream colored, with numerous dark brown lines. On top of these are several dark brown patches. It then has broken orange spots along the edge of the mantle, and an orange line along the edge of the foot. The rhinophores and gill are very characteristic, being reddish brown with opaque white specks.

Like other members of the genus the egg ribbon is a spiral laid flat against the substrate, not on edge like other chrodorids.

A large beast, I am surprised it is still undescribed. Currently its known geographic range includes the Philippine and Indonesian archipelagos.

Pirjo, Webmaster, and Francis Pellet
Nudibranch Conference, Crystal Blue Resort, May 2023

Francis and Pirjo Pellet live in Les Vans in the Rhone Valley, France. I first met Francis and Pirjo at the July, 2005 Opisthobranch Course held at Cerbere, France hosted by Robert Oms We have reconnected at various times thru the years but more recently at the Nudibranch Conference held at Crystal Blue Philippines resort in May.

I can't say enough about the Pellets and their slug hunting and photography skills although they probably don't need an introduction to readers of this site!. A good many of their finds are in the 5mm and below category which in my estimation is the ultimate challenge in sea slug hunting! Of course photographing something this small is by no means a "slam dunk" as in basketball parlance! There are focus and depth of field considerations which can drive the underwater photographer to exasperation. The Pellets , it goes without saying, excel in super macro photography of sea slugs!

Pirjo shoots with Nikon D 300, 60 mm macro lens and Subsee +10 wet lens of 15 years vintage. Her system is still doing a great job as the reader can see! Francis shoots with a Olympus TG 6 but prefers to use it in a wide angle capacity.

They have through the years contributed countless stunning images to the site for which I am extremely appreciative.
