A relatively large species of Dermatobranchus usually characterised by the often flat-topped orange tubercles on the mantle, and the orange border to the mantle and oral veil. As ilustrated here in Bob Bolland's photo, colour is variable and tubercles sometimes lack any colouration. In other specimens the tubercles are large and form raised orange rings.
