Cephalopods such as the arrow squid makes up the remainder.
The penguin’s food consists of six main species of fish:
- Blue cod
- Red cod
- Ahuru (pink cod)
- Silversides, and
- New Zealand blueback sprat
The fish caught are small between 2 and 32 centimetres long – a good size for penguins.
The opalfish, a bottom-dwelling species is found only around New Zealand. They are between 10 and 25 cm in length. It is long and slender with a flattened snout giving rise to the family name of `duckbill`.
Blue cod aren’t always blue. Their body colour varies and larger fish are bluish with greenish sides and a golden brown stripe above each eye.
Red cod are red-brown above, becoming pink on the sides and belly.
Ahuru is a small deepwater fish.
Arrow squid are mainly around the coast of the South Island and off the Campbell and Auckland Islands. Juveniles are eaten.
