Many specimens of Dendrodoris nigra are pink or orange when juvenile but black when adult.
Black adults often have clusters of white spots on the mantle and sometimes there can be a
marginal or submarginal red or pink mantle border.
Very similar is Dendrodoris fumata 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 fumata has 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.
