text: TV series "River Monsters", Jeremy Wade shows a dramatization of a snakehead, "the fish from hell", stalking an unsuspecting baby and Chihuahua. With the help of a snakehead researcher, however, Wade shows that although it is capable of living outside of water and is able to move on land, its weak pectoral muscles make movement difficult and render the snakehead an unlikely "stalker" on land. Snakehead (fish) The snakeheads are members of the freshwater perciform fish family Channidae, native to parts of Africa and Asia. These elongated, predatory fish are distinguished by their long dorsal fins, large mouths, and shiny

From a young age, "C. amphibeus" can survive in a low-oxygen water habitat, but if deprived of surface access, adult snakeheads can die from the lack of oxygen. Due to its smaller size (in comparasion to other snakeheads), the Chel snakehead is slightly easier to keep in aquaria. However, there have been several episodes when snakeheads have been released into non-endemic environments, and the danger of

text: Ceylon snakehead The Ceylon snakehead ("Channa orientalis") is a snakehead species. They are freshwater fish that grow to a maximum size of approximately , so are a member of the informal dwarf snakeheads. They originate from southwest of the island of Sri Lanka. They are predatory fish that feed on plankton, insects, and sometimes small amphibians. They can breathe on land for short periods of time because they have accessory respiratory organs through which they can use atmospheric oxygen to breathe. During wet weather, they can survive on land for more than four days, but if their bodies dry up,

text: Snakehead (fish) The snakeheads are members of the freshwater perciform fish family Channidae, native to parts of Africa and Asia. These elongated, predatory fish are distinguished by their long dorsal fins, large mouths, and shiny teeth. They breathe air with gills, which allows them to migrate short distances over land. They have suprabranchial organs which develop when they grow older, which are primitive forms of labyrinth organs. The two extant genera are "Channa" in Asia and "Parachanna" in Africa, consisting of about 40 species. They are valuable as a food source and have become notorious as an intentionally released invasive

There was concern in 2007 that snakehead fish could get into the Great Lakes area. Officials warn that if the fish invades, it could "decimate the aquatic food chain". A YouTube video mentioned in a newspaper account has a man claiming that the fish could "bite your entire hand off". The fish can reach in length and "survive out of water for four days" and

Both weather patterns emerged due to greater vertical growth of the Alps, Pyrenees, and Himalayas, which affected Eurasian climatic patterns. Snakeheads can become invasive species and cause ecological damage because in many areas to which they are not native the absence of natural enemies gives them apex predator status. Not only can they breathe air, but they can also survive on land for up to four days, provided they are wet, and are known to migrate up to 400 m (1/4 mi)

The Ceylon snakehead is, according to existing reports, a mouth brooder like many Channa species. The male carries the eggs while the female guards the territory. The male is less active during this period and is often seen close to the surface. The fry remain with the male until they can take care of themselves. Females may catch stray fry and return them to the mouth of the male.

"National Geographic" has referred to snakeheads as "fishzilla" and the National Geographic Channel reported the "northern snakehead reaches sexual maturity by age two or three. Each spawning-age female can release up to 15,000 eggs at once. Snakeheads can mate as often as five times a year. This means in just two years, a single female can release up to 150,000 eggs." "Since 2002, it has been illegal to possess a live snakehead in many US states, where they are considered a destructive invasive species." Virginia

It is a facultative air breather; it uses a suprabranchial organ and a bifurcated ventral aorta that permits aquatic and aerial respiration. This unusual respiratory system allows it to live outside of water for several days; it can wriggle its way to other bodies of water or survive being transported by humans. Only young of this species (not adults) may be able to move overland for short distances using wriggling motions. The preferred habitats of this species are

In 2012, a snakehead was found in a pond in Burnaby, British Columbia, but further study revealed that it had been released three months or less before its capture and it was a blotched snakehead or perhaps a hybrid involving that species. Unlike the northern snakehead, which potentially can establish a population in parts of Canada, the blotched snakehead generally only lives in warmer waters. Before its exact identity

The federal government in the U.S. is concerned that release of this fish into U.S. waters could harm the environment. This predator could kill native species, especially in southern areas such as Florida, Texas, and Hawaii that have a warm climate similar to Assam's climate. Accordingly, it is illegal in the United States to possess, import, or sell these fish or their eggs. Violations of this law have occurred in various states (e.g. Kentucky and Georgia).

It also enables the snakehead to travel short distances on land, although it is unable to hunt while on land, as it cannot support itself at all with its small fins in comparison to its large body. In Malaysia and Singapore, they are known locally as the "toman", while in Indonesia they are called "gabus" or "haruan" (not to be confused with another species of smaller snakehead known as the common snakehead also called "haruan"), and are cultured in fish ponds and reservoirs as

Five species ("C. argus", "C. barca", "C. marulius", "C. micropeltes", and "C. striata") can reach or more. Snakeheads are thrust-feeders that consume plankton, aquatic insects, and mollusks when small. As adults, they mostly feed on other fish (such as carp) or on frogs. In rare cases, small mammals such as rats are eaten. The Channidae are well represented in the fossil record and known from numerous specimens. They likely originated in the south

According to the United States Environmental Protection Agency, snakeheads have also been spotted in California, Delaware, Florida, Hawaii, Maine, Maryland, Massachusetts, Virginia, and Rhode Island.

The northern snakehead can double its population in as few as 15 months. It reaches sexual maturity at age two or three, when it will be about long. The eggs are fertilized externally; a female can lay 100,000 eggs a year. Fertilization occurs in shallow water in the early morning. The eggs are yellow and spherical, about in diameter. Eggs hatch after about 1–2 days, but they can take much longer at lower temperatures.

It lives in waters greater than 20 °C and is found primarily within the intertropical convergent zone. Obscure snakeheads are carnivorous fish. Adults feed primarily on other fish up to half their size, while juveniles feed on insect larvae, insects, prawns, and copepods. This fish can gain about 2 g/day and reach a weight of 1 kg within 4–5 months. An adult "P. obscura" has been measured at 54 cm. Determining
