Is a Flounder Fish Saltwater Or Freshwater?

Flounder is a type of flatfish that can be found in both saltwater and freshwater environments. However, most flounder species are more commonly found in saltwater habitats such as estuaries, coastal waters, and the open ocean. A small number of flounder species inhabit freshwater rivers and lakes.

Flatfish are unique in that they begin their lives swimming upright like other fish, but during a metamorphosis phase one side of their body grows white while the other side remains brown or dark. This causes them to swim sideways and sink to the bottom of their habitat where they spend the rest of their lives lying on one side on the seafloor. Their eyes migrate to the upper (white) side of their bodies so they can better camouflage themselves from predators and prey alike.

Flounder are important food sources for humans and other animals alike. They are often caught using trawling methods which involve dragging large nets through the water column behind a boat. This method can be harmful to other marine life and habitats, so many conservation groups are working to promote more sustainable fishing practices.
