Derwent flounder

The Derwent flounder is a flatfish of the family Pleuronectidae. It is a demersal fish that lives on sand and mud bottoms in shallow coastal waters, at depths of between. Its native habitat is the south-western Pacific, particularly the south-east coast of Australia, from New [South Wales] to South Australia and Tasmania. It grows to at least in length, and can reach up to.
