The peacock flounder, which is also known by its scientific name of Bothus lunatus, has two eyes on the left-hand side of its body. It is a member of the family of Bothidae, or “sandal flounders”, and is found in the Atlantic, Indian, and Pacific oceans.
Like other flounder species, the peacock flounder has an asymmetrical body and its eyes are located beside each other on the same side. These two eyes can be easily viewed when looking at the fish from both a top view and an aerial perspective.
The two eyes of the peacock flounder are large and prominent and are the main distinguishing features of the species.

What is the fish with 2 eyes on one side?
The fish with two eyes on one side is called a Cyclops, from the genus of the same name. They are solitary, nocturnal ambush predators found mainly in the deep waters of the Atlantic. They use the two eyes on one side in a superficially binocular vision by rotating their heads back and forth to get stereo vision.
The second eye’s purpose is to scan for predators and protrude tentacles if something is encountered. These fish are capable of eating almost anything of a size similar to them. The size of Cyclops may vary with some being 1cm long and some reaching a length of 15cm.
The genus belongs to the family of scombridae and closely resembles mackerels, swordfish, and bonitos.
Why do flounder’s have eyes on one side?
Flounder have eyes on one side due to a physiological process known as asymmetrical cranial migration. This process occurs when the eyes gradually migrate to one side of the head. This is driven by childhood growth and development of the brain, with certain physiological and neurological signals causing the eyes to move before birth.
This occurs in all flounder species and is a result of the adaptation to their environment. Flounder live on the seabed and have an adapted lateral body shape with both eyes on the upper side, which helps them to better hide from predators amongst the sediment and detect potential prey.
This has enabled them to become a successful marine species.
Do all fish have 2 eyes?
No, not all fish have two eyes. Most species of fish have two eyes, however, there are some interesting exceptions. Some of the best-known exceptions are species of cavefish, which have either evolved without eyes or have lost them over time due to lack of use.
Other species, such as stingrays, may have reduced the number of eyes they possess due to their lifestyle. Lastly, some species of deep sea fish, such as the megamouth shark, have outsized eyes which provide them with a better adapted vision than other species.
What is unusual about a flounder?
A flounder is a type of flatfish with a very unusual body structure. Unlike most fish, its eyes are located on the top of its head and its body is flattened horizontally into a disc-like shape. This shape helps it to easily hide in the ocean floor, making it difficult for predators to find.
On the underside of its body, it has a symmetrical pattern, usually of white and brown, so that it is almost indistinguishable from its environment when viewed from below. Its body is also covered in small scales that help it to blend in with its surroundings.
Flounders are also able to move by undulating their body, helping them further blend into the ocean floor, as well as making them effective swimmers.
Do flounder have 4 eyes?
No, flounder do not have four eyes. Flounder are flatfish, which means that the two eyes of one side of their head lie on the other side. This adaptation allows the fish to blend in with its surroundings and become nearly invisible.
The eyes are on opposite sides of the same head allowing them to look up and down simultaneously. The eyes and coloration of the flounder’s body allows them to “walk” on the seafloor or move slowly along the bottom while remaining as inconspicuous as possible.
The flounder, while camouflaged on one side, has various pigment patterns on its other side to help it blend in to its surrounding sand or mud bottom. Despite the presence of two eyes on one side, flounder are far from being fully aware of the 360-degree environment around it.
What’s the biggest flounder ever caught?
The largest flounder ever caught is Steve Bembas’s 54. 7 pound flounder which he reeled in from Corolla, North Carolina in 1997. It was caught as part of a survey, and held the IGFA record for 8 years before being broken in 2006.
Flounders, which are a type of flatfish, can usually reach a maximum size of around 15-20 pounds, so Steve’s flounder was an exceptionally large specimen. While it’s unlikely anyone will ever beat his record, experienced anglers can still hope to reel in some smaller, but still impressive, flounders.
What kind of fish is blind with both eyes?
The blind cave fish (also known as the Mexican blind cavefish) is a species of fish that is completely blind in both eyes. They inhabit caves and springs in Mexico, and are some of the few species of fish that can survive in the complete absence of light for long periods of time.
Their bodies are adapted for sightless living, as their eyes are completely covered by scales and their bodies are light-gray in color, allowing them to move around without being seen. They possess sensory cells on their skin that allow them to sense their environment and find food.
They feed mainly on invertebrates, such as crustaceans, worms, and aquatic insects, but they can occasionally be observed eating the eggs of other fish.
What side are flounder eyes on?
Flounders have both of their eyes on the same side of their head. This is known as “heterogenesis” and is a species adaptation to help them better blend into the bottom of the ocean. Flounders are able to move both eyes independently to look around for prey, so their movement and camouflage can be effective enough to avoid predators.
Because these fish live mostly on the ocean floor, their eyes are situated on the lateral side of their head, so they can stay close to the bottom and still have an optimal view of their surroundings.
Where are the eyes on a flounder?
The eyes of a flounder are located on the left side of its body. When it is young, both eyes are on the left side, but as it matures, one eye migrates over to the right side of the body so that it can more easily lie flat against the ocean floor while hunting prey.
This amazing adaptation helps the flounder to blend in with its surroundings and go undetected by predators. Flounders also have specialized organs on their eyes that allow them to sense pressure in the water, which can help it to detect potential prey nearby.
What fish has more than 2 eyes?
Many types of fish have more than two eyes. A prime example of this is the freshwater ridgehead, otherwise known as the polypterus senegalus. This fish is commonly found in the Nile River and nearby tributaries.
Its most notable feature is its series of paired fins along its body which make it unlike any other fish. Additionally, its most impressive feature is its extended range of vision, which comes from its extra pair of eyes.
These eyes are located on either side of the ridge-like fins and are responsible for watching the movement of its prey. The ridgehead’s extra pair of eyes can also be used to detect nearby predators that may otherwise go unnoticed.
Besides the ridgehead, there are a few other examples of fish with more than two eyes. These include the greeneye, the goldeye and the yelloweye. All these fish have a special row of eye-like structures located along the sides of their heads.
These structures are known as parietal eyes, and work together with the regular eyes to give the fish a 360-degree field of vision.
Are there any fish with 3 eyes?
No, there are no known naturally occurring fish species with three eyes. Very few animals, in general, have a third, extra eye. This includes the Lepidosiren paradoxa, an amphibious fish found in the Amazon Basin in South America, and some species of caterpillars, such as the Peckia intermutans, which feed on passionflower plants.
Neither of these creatures are fish, however.
In some instances, fish have been known to develop a third eye due to genetic mutations or insults to one or both eyes. An example of this is a Siamese fighting fish with a third eye located in the center of its head.
In a study published in the journal PLoS One, mice with a third, extra eye were created using genetic engineering.
However, in most cases, such mutations or abnormalities are typically associated with serious health problems and often lead to mortality, so having an extra eye is not likely to give a competitive advantage in the wild.
Thus, it is unlikely that fish with a third eye will be able to proliferate and become a new ‘species’.
