Odax pullus, the greenbone or butterfish, is a species of weed whiting found around New Zealand. It inhabits shallow, rocky areas with brown algae growth, mainly Carpophyllum, upon which it grazes. This species can reach a length of 40 centimetres (16 in) SL and has been recorded as reaching 1.5 kilograms (3.3 lb). It is of minor importance to local commercial fisheries.
