Formerly on the Forum as Tambja sp. 1, this species is not uncommon on arborescent bryozoans, especially Bugula dentata, and ranges from green to yellow with black longitudinal lines which are usually sunken grooves. In some specimens the black lines can be very indistinct or even absent. The rhinophores are the same colour as the background colour except for the present of a dark region at the rhinophore tip which ranges from almost black to a lighter purple. There a five or six gills which also have a background colour matching the body, and a dark or purplish tip, as on the rhinophores, but in some animals the gill lamellae can also be purplish or a darker almost black colour, giving the gills almost black edging.
