What is Channa micropeltes (Giant Snakehead Fish) ?

Snakeheads are predatory fish with surprising features. Giant snakehead is a moving hunter with sharp teeth, large mouth and strong jaw. It is named as “sea fish Agr because of its aggressive reputation. In addition to the gills, it has a lung-like organ and can breathe in the air. Fish can stay away from water for a few days. The snakehead roams the land with curved movements and moves a quarter mile to reach a new waterway. 
Other snakehead species do not have the ability to act as aggressive as the giant snakehead or on land. But they are all wild and skilled hunters, and they can all breathe in the air.
Snakeheads are native to Asia and Africa, but move to North America for pet trade and food stores selling live fish. They were seen in some waterways in the US and Canada, probably because they were released from home aquariums.
Snakeheads have a long body. Different species have different colors and patterns. However, all types of finial layouts and appearance are the same.
Snake heads have a long dorsal fin on their backs. Breast fins are located on the sides, behind their heads. Pelvic fins are located just below the chest fins on the lower surface. The anal fin is placed towards the back of the animal on its lower face and is usually about two-thirds of the dorsal fin length. As with other fish, snakeheads also have a tail fin at the end of their bodies.

Breathable Fish

Snake head has extended scales. Eyes shifted to the front of the head. These features are similar to snakes and give their name to the fish here.
Snakeheads receive oxygen as well as air. The fish use their gills to collect oxygen from the water just like any other fish. Water enters the mouths and goes to the gills on both sides of the body. Oxygen passes from water to gill tissue and then enters the blood vessels. Water comes out of the opening behind the gill cover.
The fish use a space above the gills called suprabranchial organs to breathe through the air. The fish swings from the water surface enters the suprabranchial room. Here the oxygen in the air passes into the blood vessels in the tissue covering the room.


Giant Snakehead

Giant snakehead lives in fresh water. As the name suggests, it can reach 3.3 meters in length and can be more than 44 kilos.
Fish is apparently quite variable. Fish dark gray, blue-black or black background color is marked with white, silver, blue-green. The lower surface of the fish is more colorful than the rest of the fish.
Fishes have earned a reputation as a scary hunter. Its diet consists mainly of other fish, but also eats frogs, crustaceans and even birds. According to research, more animals are killed than they eat.
Giant snakeheads form a nest by clearing a cylindrical area in the middle of aquatic plants. When eggs are laid, they rise above the water column and are carefully protected by adults.

North Snakehead

Although classified in the same genus, the North snakehead and giant snakehead seem to be quite different from each other. The northern serpentine has a tan, brown, gray or gray-green background color, covered with dark spots and lines. The body is in the torpedo shape and the top of the head is visibly flattened. The lower jaw of the fish is outside the upper jaw.
The northern serpentine is native to China, Korea and Russia and has spread to other parts of Southeast Asia. Live in areas where the water is muddy and slow or stagnant. It is mainly fed with other fish, but also contains crustaceans and beetles. Like the giant snakehead, it is often referred to as “wild Dev.
There is some debate about how the fish moves on land. There is a claim that he can live on land and live three or four days away from the water, provided he stays humid like giant snakeheads. Many researchers, the water out of the water can not get away and under normal circumstances, only a few hours in the air can live says.

Reproductive

In 2007, a northern snakehead nest was found in the US Potomac River. The nest was a cylindrical water column surrounded by a water plant called Hydrilla. On a circular mat Hydrilla nest formed a roof. Orange-yellow eggs were laid on the canopy. The eggs were not sticky and kept in place. The plant is hidden by leaves and trunks. Adults, both male and female, patrolled the water under the canopy.
North snakehead nests were also found in other regions. They were cylindrical slots surrounded by vegetation and approximately one meter in diameter. However, there was a canopy in these nests.
Fishes show high yields, and leaves 22,000 to 115,000 eggs at a time. They breed up to five times a year.

Wild Snakesheads in North America

Wild snakes, including giant snakesheads, are seen periodically in various parts of North America.
The northern snakehead is found in the Potomac river and the side branches of the state of Maryland. Giant serpent has established himself in part of Florida. Adults of this species have red eyes and a black spot on the base of the caudal fin surrounded by orange. The stained snakehead lives in Hawaii and looks like the northern serpent.

An Invasive Snakehead in British Columbia

In 2012 a snakehead living in a pond in Central Park in Burnaby was discovered. The fish are hunted by partially discharging the pool.
Concerns have been raised that the fish is a northern serpent. However, in November 2013 fish was identified as spotted snakehead.

Dangers of Invasive Populations

The presence of wild snakes in North America is alarming for some guards and officials. Fish do not have natural hunters.
The presence of invasive species should always be taken seriously. Snakeheads have the potential to create an environmental problem. The areas they are invading should be closely monitored.
In Maryland, authorities appealed to the public for control of the northern serpent population. They promote the taste of the meat of the snakehead to promote fishing and organize sport fishing competitions.
