The peacock flounder (Bothus mancus), also known as the flowery flounder, is a species of fish in the family
Pacific.[2]
Description
The peacock flounder is also called flowery flounder because it is covered in superficially
lefteye flounders have both eyes on top of the left hand side of their heads. The eyes are raised up on short stumps like radar dishes, and can move in any direction independent of each other. That feature provides flounders with a wide range of view. One eye can look forward while the other looks backward at the same time. The baby flounders have one eye on each side of their bodies like ordinary fish, and swim like other fishes do, but later on, as they undergo maturation to adulthood, the right eye moves to the left side, and flounders start to swim sideways, which gives them the ability to settle down flat on the bottom.[3][4] The maximum length of this flounder is about 45 centimetres (18 in).[2]
Habitat
Peacock flounders are mostly found in shallow water on sandy bottoms. Sometimes they rest over piles of dead corals or bare rock. They may be found as deep as 150 meters (490 ft).[4]
Behavior
Diet
As most flounders, the peacock flounder is mainly
nocturnal,[2] but is sometimes also active during the day.[3] It hunts for small fish, crabs and shrimp.[3]
Reproduction
Peacock flounders
eggs float close to the surface, carried by the currents, and hatch in 15 days. Before hatching the eggs sink to the bottom. For the next four to six months baby flounders float in the open ocean, sometimes hundreds of miles from the place the eggs were released and hatched. During those months the right eye of the juvenile slowly moves to the left side.[3]
Color change
predators. Whenever possible rather than swim they crawl on their fins along the bottom while constantly changing colors and patterns. In a study, peacock flounders demonstrated the ability to change colors in just eight seconds. They were even able to match the pattern of a checkerboard they were placed on. The changing of the colors is an extremely complex and not well understood process. It involves the flounder's vision and hormones. The flounders match the colors of the surface by releasing different pigments to the surface of the skin cells while leaving some of the cells white by sequestering those pigments. If one of the flounder's eyes is damaged or covered by sand, the flounders have difficulties in matching their colors to their surroundings. When hunting or hiding from predators, the flounders bury themselves in the sand, leaving only the eyes protruding.[3][5][6]
