Paradoris dubia (Bergh, 1904)

Images taken at Frenchman’s Beach and Bare Island, NSW, Australia.

The body is white with varying amounts of brown pigmentation. There are greyish brown blotches scattered over the dorsum which encircle a ring of white glands, which themselves surround a low rounded pustule. These glandular structures are very characteristic of this species and greatly vary in number, some animals. Some have them scattered over the dorsum, while other animals have just a few down each side of the mantle skirt.

There are 7-9 tripinnate gills. They are transparent with brown speckling, and when extended are relatively small for the size of the animal. The rhinophore clubs are dark brown or black.
