Yellowbelly Flounder: We will have to believe them about having a yellow belly as this photo shows no sign of it. Anyway,  they apparently have a dark olive green body above with yellow or white on the belly and dark spots. Yellowbelly Flounder are fatter, have smaller eyes and larger, dark-edged scales than the Sand Flounder.

They are a shallow-water fish found at depths of up to 50m.

Here is the best bit – they have moist, delicate flesh with a low oil content.  Upper fillets are slightly darker than the underside but whiten on cooking.

With that in mind, HERE is a recipe from the SBS website.
