Flounder lie on the bottom in wait during the day, relying on their camouflage to keep them safe. They cover them selves partially in sand or mud and can even change their appearance rapidly to blend in. Easily identified by their flat diamond shape they tend to appear mottled above and white below. They are commonly found around the harbour entrance, and in some estuaries and bays.

Scarlet wrasse have three different colour phases for each juveniles, females and males. All have a scarlet head with white below and a black wedge on the tail. They are most abundant below 15m amongst reefs, boulders and crevices and commonly seen at Aramoana. Diet consists of small invertebrates such as crabs, brittle stars and sea urchins. Juveniles and females sometimes act as cleaner fish.

They grow rapidly maturing at 1 year of age. Females also can change sex at around 4years old. Scarlet wrasse may grow up to 40cm in length.

Grows to lengths of up to 65cm

Southern bastard cod  

Southern Bastard Cod

Pseudophycis barbata

FISH and Mammals
