In the U.S. state of Georgia in the private pond was discovered a species of fishthat can survive up to four days on land, while at the same time without the usual for their type of source water. We are talking about dangerous and predatory fish — the North Seagrove, which has an insatiable hunger and, thus, able to disrupt the ecological balance in ponds, streams and rivers. In addition, fish have a good survival rate and fecundity, thereby increasing the complexity of the extermination of this species of fish from water bodies of North America.

Having a fairly large body, they have an incredible appetite and is capable of eating other fish, marine animals, some mammals and even birds. Due to well-developed jaws with many sharp teeth, snakehead competes with its natural rivals, later becoming full owner of the pond.
In addition to gills, from the fish family snakehead has nadzhabernoy air bag for the air. Of a kind of lungs, oxygen enters the bloodstream, providing the vital functions of the body. Stock air nadzhabernoy bags enough for 3 to 5 days.
If snakehead were in adverse conditions, for example the drying up of the pond, he is able to bury themselves in muddy sediments at a depth of 1 meter, creating a camera, greased with a special mucus, where the ability to calmly wait for the filling of the reservoir up to several months. If the reservoir run out of food, the snakehead is able to overcome distances of tens of kilometers in order to find a new place of residence in the form of a river, Creek, pond or lake.
