Description

The fringed flounder is a flatfish from the southwest Atlantic, along Brazil (Rio de Janeiro) and Argentina (Patagonia). The species grows to about 40 cm and has the typical asymmetric flatfish body with both eyes on one side. As a bottom-dweller it lives on the continental shelf between about 5 and 150 metres depth and migrates to spawning grounds in spring and to feeding grounds further offshore in autumn. It feeds on amphipods, small crabs and bristle worms. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
