Dendrodoris fumata often has large blackish patches on a lighter background, but unfortunately this is not exclusive to this species. There are 5 or 6 large branching gills which often spread from one side of the mantle to the other and are situated in some distance from the extreme posterior end. There are small papillae on the skin of the mantle, which are usually black.
This juvenile specimen was identified by Dr. Richard C.Willan.
Very similar are
Dendrodoris nigra which can externally be distiguished by the shape of the body when crawling: Dendrodoris nigra is more elongate. Another feature is the position and nature of the gills: In Dendrodoris nigra the gills are relatively numerous and form a compact circle around the anus at the extreme posterior end of the dorsum.
Dendrodoris arborescens which has a black body without white spots and a marginal orange/red band.
This species was published on 19 May 2004 on these websites as Dendrodoris fumata (Rüppell & Leuckart, 1828) [Doris],
I know since a few days that Rüppell & Leuckart (1828 - 1830) is online, see reference. This text was published in 2 parts,
the pages 1 - 22 in 1828, and the pages 23 - 47 in 1830. Doris fumata appears on page/Seite 29 and on plate/Tafel VIII,
that is the year must be 1830.
I changed it on 11 January 2016 into Dendrodoris fumata (Rüppell & Leuckart, 1830) [Doris].
