This is a large species of Tambja growing to about 70mm long. It is usually black with blue markings, but this dark green colour is found in specimens from the cooler waters of New South Wales, Australia, and northern New Zealand. Like all species of Tambja, it feeds on arborescent (plant-like) bryozoan colonies.
