Wreckfish

This illustration is loosely based on the famous hāpuku, hapuka or whapuku, Polyprion oxygeneios, is a wreckfish of the family Polyprionidae, found around southern Australia, Chile, Tristan da Cunha, and New Zealand at depths between 30 and 800 m. Its length is between 60 and 180 cm, and it can weigh up to 100 kg.
Hāpuku are grey in colour with silvery white underbellies, with juveniles generally being blue in colour. They have 10 dorsal spines running along their back, a rounded anal fin and rounded pectoral fins, and a large, powerful, square-shaped tail. Its lower jaw protrudes from the top, and their very large eyes are adapted for hunting and inhabiting low-light conditions.
