Dermatobranchus fortunatus is characterized by its white body with a series of dark brown patches along the mantle margin.
It differs from many species of Dermatobranchus by the lack of obvious longitudinal ridges and grooves. There is a diffuse orange
band at the mantle margin. The rhinophores bear longitudinal perfoliations, are white at the base, the main part is black with some orange pigment, the tips are orange.
The oral veil is white with a single brown patch on the anterior end, and a diffuse orange marginal patch.
