Large ovate dorid with broad mantle skirt. The mantle is covered with rounded tubercles of varying sizes. The tubercles have a rather characteristic shape with a rounded terminal knob, then a narrower waist and then a basal stalk which itself widens to about twice the width of the 'waist' at its base. The background colour of the mantle is a translucent watery brown with scattered dark brown patches. I some animals the patches coalesce so that much of the background is a dark reddish brown. The tubercles usually have a dark purplish knob, while the basal stalk is a translucent watery brown, often with an opaque white ring around the base. Species of Carminodoris are characterised by the possession of jaws, denticulate outer radular teeth, a large prostate gland, and an armed penis. C. armata lacks the denticulate radular teeth but its name armata refers to its penis which is armed with many hooks. See Carminodoris bifurcata.
