The greenback flounder, rhombosolea tapirina, is commonly found on sandy flats to depths of 100 metres.

They are a part of the righteye flounder family, found around southern Austraila and New Zealand. They are called ‘righteye flounders’ because most species lie on the sea bottom on their left side with both eyes on the right side. They grow to approximately 38cm in length; they reach their maximum size at 3-4 years of age.

Females lay eggs that float in mid-water until the larvae develop before they sink to the bottom. Young flounders have eyes placed normally but as it grows it starts to lie on one side and the eye travels across to the other side of its head and its mouth becomes twisted.
