The types of fish that swim in our lakes, rivers, seas and our oceans are characterized by unique adaptations and characteristics, some of which are able to camouflage to protect themselves from predators, while others are characterized by a streamlined anatomy, which facilitates moving quickly through water.
But it is widely unknown adaptations that some fish have the ability to survive outside the water, breathe air, and transit the road literally. While not all fish are able to breathe outside the water, some species have this ability.
Breathing out of water
The majority of fish that are able to live and breathe outside the water are usually classified as an amphibious, and they have unique properties that help them breathe and even move over the surface of the water and on land.
The length of the time of the fish is alive outside the water of its type. Some of them can breathe out of the water for a few hours, while others may remain outside it for continuous days without breathing problems, and the “mangrove” fish can, for example, live outside the water for up to 66 days.
This unique fish breathes through its skin and gills, and allows it to move on the land by launching, swaying and swooping.
This fish has a specialized skin that performs many roles of gills, such as maintaining salt levels, and the skin also contains blood vessels located one micron from its surface, allowing the absorption of more oxygen in the blood.
This strange fish usually lives in a little salinity, but when the surrounding environment dries up, or when its prey is chased, it is decided to leave the water and hide inside the tree trunks, and it usually does it in groups until it becomes stacked like sardines.
Endouits designed for walking
There is also a clay frying fish, which is an amphibious fish that is adapted with living and movement on land and water. These creatures have many interesting adaptations, including their ability to breathe through their gills and skin, and have special chest fins that they use as legs to walk on the ground.
This fish can stay outside the water for up to two continuous days, eat and interact with each other, defend its land, and the male performs an additional task, which is the puffs of oxygen on the eggs.
The male ascends to the surface to inhale the air that is not inside the hole that he built, then spoils it with all its strength, and returns the ball many times, until the air needed to hatch the eggs.
After a heavy rain storm, it is fashionable to see the “cattle” catfish “writhing like a snake across the road, and folds its body back and forth to jump on the land.
As its name suggests, this type of fish is scientifically known as “Claarias Patrakos” can move outside the water and walk via land, as its thorny chest fins provide an additional payment force – such as feet – to move itself.
This dark, dark fish is uniquely adapted to the ability to move on land. It can travel up to 3 quarters of miles, and you will not need to return to water for up to 18 hours, which gives it a great opportunity to move between different water places.
This type of fish is characterized by the presence of a special gills brown or lung -like organs that allow it to breathe outside the water, and bear harsh living conditions, and it can leave the water and walk or crawl to a place better as long as wet.
Although it prefers warm freshwater habitats in its original homeland in Southeast Asia, it has succeeded in invading other regions, and this may be one of the reasons for its ability to “walk” outside the water.
Why do fish do that?
Fish leaves water for many reasons, such as escape from predators or low oxygen environments.
Taste catfish loves to move from one water flat to another in search of a better food or analgesic, and do so by swaying on land, while the “clay fold” fish spends on land for feeding, then returns to water to multiply and avoid predators attacks.
Picco (hyibostomas picostomas) sometimes needs to move according to the availability of prey and water levels, and for this reason – according to the estimates of scientists – can stay outside the water for up to 20 hours during his transfer.
According to a recently published study in the journal “Biological Litters”, the small mangroves cools its heat with jumping outside the water. This fish lives in tropical climates, and when the water is warm, it jumps out to lower its body temperature by cooling itself with air.
Snake head fish is transmitted to “more green pastures” in search of a partner or food, or if the current source of its water is depleted, while the “four -eyes fish” climbs muddles to feed on insects, and the famous “Gronone” fish comes to the beaches of California to multiply.
