There are many things on our earth that surprise a person. For example, here you can include interesting facts from the life of fish, and here are some of them.
List of the best…
The whale shark rightfully takes the place of the largest fish. It is found in three oceans - Indian, Pacific and Atlantic. Its main diet is plankton. The largest specimen from this family was found in 1949. When measured, she was 12.65 meters long.
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 fished out of the water, he was (estimated) three years old. This happened in 1860.
The next interesting fact about fish may be familiar to some. The most dangerous and bloodthirsty among freshwater are piranhas. They stay in flocks and attack the victim together, regardless of its size. They live in South America. In Brazil in 1981, there was a shipwreck, and three hundred people fell into the water. No one survived because there were piranhas there.
The fastest inhabitant of the water depths is the sailfish. InFlorida organized tests that confirmed this fact. In just three seconds, this fish overcame 91 meters. Her speed reached 109 km/h.
Amazing fish
There are fish on our planet, the existence of which many do not even know. Here are some of them. There is a fish that freely comes out of the water and moves on land. It is called anabas. Without water, she can stay up to eight hours. The fins help her move. The climbing perches come out of the water to find food or move to another body of water. They can also climb trees.
There is another interesting fact about fish related to eels. Some of their subspecies are able to swim backwards. The rest of the fish do not know how to do this “trick”.
The taste sensations of stingrays are superior to those of humans. While humans have only 7,000 taste buds, this fish has 27,000.
Fish are "water drinkers". Every day they consume an amount of liquid equal to their own weight.
There is a predator who always has a "fishing rod" with him. The monkfish has a protrusion on its head that it uses to lure fish.
Unbelievable but true
It is worth paying attention to other interesting facts about fish that seem incredible at first glance. So, it is known that these creatures can also drown. If there is a small amount of oxygen in the water, the fish may suffocate, since air is important for its life.
There is a very unusual subspecies in the imperial angel family. Males have multiple wives. But if he dies, the female takes his place. The most amazing thing is that she changes her gender to lead the "harem".
How to tame a fish
Another interesting fact about fish is that 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 worth feeding it daily at the same time and at the same time making a certain sound, for example, knocking. After a few days, your pet may develop a tapping reflex that tells him it's time to eat.
About cartilaginous fish
Cartilaginous fish are an unusual class. Interesting facts about these aquatic inhabitants help broaden your horizons. To begin with, it is worth noting that this class of fish was classified as a bone brethren for a long period.
Many species of their representatives today are inhabitants of oceanariums.
Representatives of some species of this class emit poisonous substances with their glands that can harm a person, and if help is not provided within a short time, the victim will die.
Cartilaginous fish are characterized by internal fertilization.
About sharks
The most famous cartilaginous predators are sharks, but despite this, the facts about them are very interesting. For example, these fish almost always feel hungry. They can eat anything they see, even their own innards, which fell out of the open stomach.
Strange things have been found in the belly of this predator more than once that do not harm her. These are suitcases, and horseshoes, and pots.
The structure of the shark is also of interest. Her jaws and skull are not connected to each other, therefore, if necessary, for example, before a bite, she pushes them forward. In addition, they have no bones at all.
Male blue sharks bite females during courtship, and therefore their skin is three times thicker than that of males.
Flying fish
Another representative of the underwater world is flying fish. Interesting facts about her are also impressive. These fish have large fins that help them soar above the water surface for a while. During the flight, their speed can increase to 80 km / h. These fish soar in the air for an average of 50 meters. But with luck, they are able to extend the flight due to the trapped air flow. Thanks to the fins, fish can change the direction of flight. The caviar of these creatures is widely used in Japan for making sushi. It's called tobiko.
Clownfish
Another unusual representative of the marine fauna is the clownfish. Interesting facts about these creatures are very bright and entertaining. Despite its small size, this fish is very brave and staunchly defends its territory from intruders. She is ready to fight even with divers, whom she perceives as encroachers on her property. In his anger, the clown can even bite a person (the teeth of the fish are not sharp). Factis also that the territory is guarded only by females. These representatives of fish live in anemone corals. Despite their warlike disposition, they are afraid to swim away from their house more than a meter. After the death of the female, some "boys" change sex. All fry are born male, only with time some of them turn into "girls".
Pisces in antiquity
Here are some more interesting facts about fish and how they were perceived by people in the past:
- The monks of the Middle Ages were sure that the beaver was a fish. This animal was on their menu during the fasting period.
- Romans and Greeks thought that rays had extraordinary energy, because in those days people had no idea about electricity.

- Let's give another interesting fact about swordfish. It is known that they attacked and still continue to attack ships. In the past, ships have sunk from these assassination attempts, as swordfish can pierce the plating, even made of two centimeter steel. From her blowthere remains a gap 25 centimeters in diameter.
