Distinguishing features

Bill Rudman notes in Sea Slug Forum: "The animal is usually a translucent green colour with a black parapodial margin and a submarginal yellow or orange band. Sometimes there is a white line between the orange and yellow bands. The tip of the rhinophores often have the same colour bands. There are also numerous black and white dots all over the body."
