Distinguished by the black edge to the parapodial flaps. Background colouration can be yellow, green, brown or red, depending on the colour of the host seaweed on which the animal is feeding. The species is, however, easily recognised by the black trim to the parapodia and the black tips to the oral tentacles and rhinophores. It also is a relatively small sea hare, whose parapodia commence a long way back along the body. Like many other opisthobranchs, it is sporadic in appearance, being extremely abundant at some sites for several months and then not being seen again for several years.
