In the US state of Georgia, a fish species was found in a private pond that can live on land for up to four days without the usual source of water. We are talking about a dangerous predatory fish – the northern snakehead, which has an insatiable hunger that can disturb the ecological balance in ponds, streams and rivers. In addition, the fish has good survival and fertility, increasing the complexity of extinction of this species from North American waters.
Large rivers of the Far East are the historic home of the serpent heads, but thanks to humans, these fish found themselves in the countries of Central Asia, Africa and the United States. They have a fairly large body, are incredibly carnivorous and can eat other fish, marine animals, some mammals and even birds. Due to the developed jaw with many sharp teeth, the snake head can compete successfully with its natural competitors and becomes a full-fledged host of the reservoir.
In addition to the gills, the Snakehead fish have a sub-gill air bag for atmospheric air. Oxygen enters the bloodstream via the peculiar lungs, thus ensuring the vitality of the body. The air supply in Suprajug bags takes 3 to 5 days.
Was the snake head in an unfavorable condition, z. B. a dry pond, it can be buried in muddy sediments to a depth of 1 meter and create a lubricated with special mucus chamber in which he can wait quietly for several months for the replenishment of the reservoir. When the food in the pond runs out, the snakehead can cover distances of several tens of kilometers to find a new location in the form of a river, creek, pond or lake.

The Ministry of Natural Resources is concerned about the appearance of this fish in a private pond in Georgia, as it threatens not only the extinction of some fish species from the reservoir, but also the spread of a dangerous predator that destroys everything on its way. Scientists are currently trying to find out if this type of fish reaches beyond the reservoir. The number of snake heads is regulated by federal law and is classified as a harmful wild animal. Such classification means that the illegal importation of this type of fish into the United States is prohibited without a specific license.
At the same time, in the rivers Amur and Ussuri in Russia, the snake head is a valuable commercial species and exists quietly with both predatory and peaceful fish species. Fish belonging to the snakehead family do not pose a threat to humans, but there have been cases in which they have been able to attack humans and protect their offspring.
