When flounders swim near the surface to feed, their skin becomes almost see-through. This helps them avoid predators below them. When they swim near the bottom, their skin can imitate the different colors and textures found on the seafloor. They can look like sand one minute, and a rocky bottom the next!
How do flounders protect themselves?
Camouflage and reproduction
The fish expand and retract their chromatophores—pigment-containing cells—to quickly change color if threatened or stalking prey. They can also bury themselves quickly in the sand, protruding their independently moving eyes to keep watch without being seen.
How do sea creatures protect themselves from predators?
Many ocean animals have the amazing ability to camouflage themselves to blend in with their surroundings. Camouflage can help animals protect themselves from predators, as they can blend into their surroundings so a predator may swim by without detecting them. Camouflage can also help animals sneak up on their prey.
How do animals camouflage in the ocean?
Animals inhabiting the open ocean often conceal themselves by being highly transparent, but this transparency is compromised by light that is scattered and reflected from the body surface. New research shows that some midwater crustaceans use antireflection coatings to enhance their invisibility.
How do flounders reproduce?
They spawn by a method known as broadcast spawning, where females and males release their eggs and sperm into the water column at the same time. This method increases the likelihood that the eggs will become fertilized and decreases the chances that fertilized eggs will be eaten by egg predators near the seafloor.
Does a flounder have any predators?
The flounder is an ambush predator that lies motionless on the ocean or sea floor, blending in with the environmental surroundings, and then quickly snaps up the unsuspecting prey with its sharp teeth.

How do fish respond to danger?
Fish warn each other about danger by releasing chemicals into the water as a signal, research by the University of Saskatchewan (USask) has found. The USask researchers discovered that wild fish release chemicals called ‘disturbance cues’ to signal to other fish about nearby dangers, such as predators.
How do whales defend themselves from Orcas?
Again, by traveling in numbers, whales make it harder for sharks or orcas to target a specific member. If they feel threatened, though, whales will form a circle with their head facing inward, tail facing out. This allows them to protect the young in the middle while attacking with their tail from behind.
Do flounder change colors?
They are experts at camouflage and can quickly change colors to match their surroundings. If the flounder is blind or has a damaged eye, it has trouble camouflaging itself against its background because it can’t see it.

What is unique about flounders?
The flounder is morphogenetically unusual. When born it is bilaterally symmetrical, with an eye on each side, and it swims near the surface of the sea. After a few days, however, it begins to lean to one side, and the eye on that side begins to migrate to what eventually becomes the top side of the fish.
