Orthorhombus

Orthorhombus is a genus of flatfish belonging to the family Bothidae, commonly known as left-eye flounders. These fish are characterized by their rhomboidal body shape, hence the genus name, which is derived from Greek words meaning "straight" and "shape." Species within Orthorhombus are found in the Indo-Pacific region, inhabiting sandy or muddy bottoms in coastal waters and continental shelves. They are demersal, meaning they live on the seafloor, where they employ camouflage to blend in with their surroundings.

Like other heterosomats, Orthorhombus species are asymmetrical, with both eyes migrating to one side of the head as they mature, typically the left side, although some exceptions exist. This allows them to lie on the seabed with both eyes directed upwards, scanning for prey. Their diet primarily consists of small crustaceans and fish. Orthorhombus species are generally considered commercially important in certain parts of their range, often caught using trawls and other bottom-fishing gear. Examples of species include Orthorhombus russellii and Orthorhombus tetragonolepis.
