It makes it harder for predators (animals that eat other animals) to see the flounder when it is swimming. Flounder can also change color to match the background. This is called camouflage. Flounder have tiny sacks of pigments (colors) in their skin.
How do fish protect themselves?
When they sense danger they fill their stomachs with water (or air if they are out of water). This exposes sharp spines that cover their bodies. This makes them less inviting for predators to catch. Their skin and some internal organs contain tetrodotoxins, which are highly toxic substances.
Do flounders have eyes?
Eye migration
Larval flounder are born with one eye on each side of their head, but as they grow from the larval to juvenile stage through metamorphosis, one eye migrates to the other side of the body. As a result, both eyes are then on the side which faces up.
Why do flatfish camouflage?
Their pigment also changes, making them light on their belly side and dark on their back—a type of camouflage called countershading. Once this change is complete, the fish will settle onto the seafloor, its dark back blending into its surroundings and its eyes well positioned for spotting predators or prey.
Do flounders swim flat?
When a flounder is young, its body looks a lot like other fish: an upright body and an eye on each side. However, as a flounder grows older, its body changes…. a lot! It changes to swimming flat on the ocean floor (it can hide itself this way) and both eyes are on the top of its body.
What are three ways fish protect themselves from predators?
Many fish also form a school of hundreds or thousands of small fish to protect themselves. Fish use their five senses, and some have spines or venom. The defense tactics they use affect their behavior and their coloring, how they use their surroundings, and their body form.
Do fish protect each other?
Fish chase each other for a variety of reasons, such as defending their territory, establishing dominance, competing for food, and mating.
What is the fish with 2 eyes on one side?
flatfish
A flatfish is a member of the ray-finned demersal fish order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development.
What eats a flounder?
Young flounders are fed upon by crabs, shrimps, and other fish while juvenile and adult flounder fall prey to many predatory fishes including cod, sculpin, striped bass, bluefish, cobia, groupers, moray eels, skates, stingrays, and sharks.
Can flounder see color?
It is not completely clear how these animals are able to change there color to match their environment. It looks like peacock flounder use their eyes to see the pattern in the environment and then change the pigments that show on their skin to match their surroundings.
How does a flounder camouflage?
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!
Why does a flounder have two eyes on one side?
Do you know why? Wikipedia explains “as an adult, a flounder changes its habits and camouflages itself by lying on the bottom of the ocean floor as protection against predators. As a result, the eyes are then on the side which faces up. The side to which the eyes migrate is dependent on the species type”.
Why do flounder swim sideways?
Schartl’s team also revealed that in the late larval stage, the fish swims upright but with a slight sideways tilt, so that sunlight hits it unevenly. This activates opsins to a greater extent on one side, leading to the eye and skin colour asymmetry that eventually allows the fish to flip sideways.

Where do flounder go in the winter?
Winter flounder migrate from offshore areas to nearshore waters in winter, which is where they get their name.
What type of fish is flounder?

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.
What is the biggest threat to fish?
Seven of the Biggest Problems Facing Fish in Our Oceans
- Overfishing. Whether it’s for the food industry or the aquarium industry, overfishing is a serious threat to the fish in our sea.
- Ocean Acidification.
- Ghost Fishing.
- Commercial Whaling.
- Plastic.
- Irresponsible Fish Farming.
- Habitat Destruction.
How do deep sea creatures avoid predators?
In the deep sea, animals’ bodies are often transparent (such as many jellies and squids), black (such as blacksmelt fish), or even red (such as many shrimp and other squids). The absence of red light at these depths keeps them concealed from both predators and prey.
Do fishes cry?
“Since fishes lack the parts of the brain that set us apart from the fishes — the cerebral cortex — I doubt very much that fishes engage in anything like crying,” Webster told LiveScience. “And certainly they produce no tears, since their eyes are constantly bathed in a watery medium.”
Can fish hear you when you talk to them?
However, yes, they can hear your voice.
They just know someone is speaking. They can associate sounds with action, though. For example, if you are to say your betta fish’s name – let us call him George – each time you sprinkle food in his aquarium, he will eventually associate the sound of “George” with food.
