On our earth there is much that causes a man of surprise. For example, here you can include interesting facts about the life of fish, and here are some of them.
Whale shark takes its place by itselflarge fish. It is found in three oceans - Indian, Pacific and Atlantic. Its main diet is plankton. The largest caught individual from this family was discovered in 1949. When it was measured, it reached a length of 12.65 meters.
The oldest fish was 88 years old. It was an eel that died in 1948. He lived in the Swiss Museum in an aquarium. When he was caught out of the water, he was (according to rough data) three years. This happened in 1860.
The next interesting fact about fish, perhaps,some will already be familiar. The most dangerous and bloodthirsty among the freshwater are the piranhas. They keep flocks and together attack the victim regardless of its size. They live in South America. In Brazil, in 1981, a shipwreck occurred, and three hundred people fell into the water. No one could survive, as there were piranhas.
The fastest inhabitant of the water abyssesis a sailfish. In Florida, tests were organized, which confirmed this fact. In just three seconds, this fish overcame 91 meters. Its speed reached 109 km / h.
On our planet there are fish, about existencewhich many do not even guess. Here are some of them. There is a fish that freely leaves the water and moves overland. It is called anabas. Without water, it can stay up to eight hours. Help her to move fins. The Anabas go out of the water to find food or to move to another pond. They can also climb trees.
There is another interesting fact about fish associated with acne. Some of their subspecies can swim backwards. The remaining fishes can not do this "trick".
Taste sensations skates surpass human. At that time, as a person taste buds there are only 7 thousand, this fish has 27 thousand.
Pisces are "waterbirds". Every day they consume a quantity of fluid equal to their own weight.
There is a predator who always has a "fishing pole" with him. At the sea level on the head there is an outgrowth that he uses to lure the fish.
It is worth paying attention to other interestingfacts about fish that seem at first sight incredible. So, it is known that these creatures can also drown. If there is a small amount of oxygen in the water, the fish can suffocate, since air is important for its vital activity.
In the family of imperial angels there is a veryunusual subspecies. The males have several wives. But if he dies, the female takes his place. The most surprising thing is that she changes her gender to head the "harem".
Another interesting fact about fish isthat they can be tamed. Of course, this applies to aquarium inhabitants. This is possible if the fish develop a reflex. To do this, it is necessary to feed it at the same time every day and at the same time make a certain sound, for example, a knock. A few days later your pet may have a reflex to tapping, which tells him that it's time to eat.
An unusual class are cartilaginous fish. Interesting facts about these water inhabitants help to broaden the horizon. For starters, it should be noted that this class of fish for a long period was considered to be bone relatives.
Many species of their representatives today are inhabitants of oceanariums.
Representatives of some species of this classthey give off their glands venomous substances that can harm a person, and if they do not help in a short time, the victim will die.
Cartilaginous fishes are characterized by internal fertilization.
The most famous cartilaginous predators aresharks, but, despite this, the facts about them are very interesting. For example, these fish almost always feel hungry. They can eat whatever they see, even their own insides that have fallen out of the ripped belly.
In the belly of this predator, strange things have been repeatedly revealed that do not harm her. These are suitcases, horseshoes, and pans.
The structure of the shark is also of interest. Her jaws and skull are not connected to each other, so if necessary, for example, before a bite, she pushes them forward. In addition, they have no bones at all.
Males of blue sharks during courtship bite females, and therefore their skin is thicker than three times that of males.
Another representative of the underwater world isflying fish. Interesting facts about her are also impressive. These fishes have large fins that help them soar over the water surface for a while. During the flight, their speed can rise to 80 km / h. These fish float in the air on average 50 meters. But if you're lucky, they are able to extend the flight due to the caught airflow. Thanks to fins, fish can change the direction of flight. Caviar of these creatures is widely used in Japan for making sushi. It's called tobiko.
Another unusual representative of the marine faunais a clownfish. Interesting facts about these creatures are very bright and entertaining. Despite its small size, this fish is very brave and steadfastly protects its territory from uninvited guests. She is ready to engage in combat even with divers, whom she sees as an assault on her property. In his anger, a clown can even bite a person (the teeth of a fish are not sharp). It is also a fact that the territory is protected only by females. These representatives of fish live in corals-actinia. Despite their militant temper, they are afraid to sail away from their house more than a meter. After the death of the female, some "boys" change their sex. All fry are born male, but over time, some of them turn into "girls".
Here are some interesting facts about fish and how people perceived them in the past:
