Unbelievable but true

It is worth paying attention to other interesting facts 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.

About cartilaginous fishes

An unusual class are cartilaginous fish. Interesting facts about these water inhabitants help to broaden the horizon. To begin with, it should be noted that this class of fish for a long period was considered to be bone relatives.

Cartilaginous fishes differ 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 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 found 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.

Fish that can fly

Another representative of the underwater world is the flying 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.

Clown fish

Another unusual representative of marine fauna is 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 enter into battle even with divers, whom she perceives as encroachments 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 active corals. 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."
