Description

The blue cod, so called in New Zealand, is a bottom fish of the sandperch family (Pinguipedidae) endemic to New Zealand. Despite the name it is not a true cod. The species reaches about 45 cm and has an elongate, blue-grey body with a large head. It inhabits rocky areas to about 150 m deep and is home-ranging. It is a predator that catches small fishes and crabs by stalking and swallowing them whole. The species is a protogynous hermaphrodite and one of the most important recreational and food fishes of New Zealand.
