Most other snakeheads reach between 30 and 90 cm (12 and 35 in). The dragon snakeheads have “a whole series of primitive characteristics,” and are rightly called “living fossils,” says David Johnson, an ichthyologist at Smithsonian’s National Museum of Natural History in Washington, D.C., who wasn’t involved in the paper.

 The Gollum snakehead, named after the subterranean character in Lord of the Rings, is one of two species in a newfound taxonomic family of fishes.
 In about 120 mi (190 km) of river, the population has surpassed 21,000 individuals. Researchers have discovered a new family of eel-like fish, named dragon snakeheads, which live in underground waters in southern India.
This family includes only two species, one of which is named the Gollum snakehead, after the subterranean Lord of the Rings character. In rare cases, small rodents such as rats are eaten.
Not only can they breathe air, but they can also survive on land up to four days, provided they are wet, and are known to migrate up to 400 m (1/4 mi) on wet land to other bodies of water by wriggling with their bodies and fins. Courtenay, Jr., Walter R. and James D. Williams. tools & documentation, All sites, services & They breathe air with gills, which allows them to migrate short distances over land. Called nga yant in Burmese, in Manipuri as ngamu, they are prized fish eaten in a variety of ways.
Shortly thereafter, another researcher found a second species in that genus as well, based on a single specimen—the Mahabali snakehead. sites, services & tools, Flora researcher found a second species in that genus as well, Related: World’s largest cavefish discovered in India.
Raghavan sent the photo to Britz, who had “no idea what it was,” Britz says—not the species, genus, or family. In Indonesia, snakehead fish are called ikan gabus, served as the main parts of traditional dishes such as Betawis' pucung gabus, and considered to be a delicacy due to their rarity in the wild and in aquaculture, as they are harder to raise than other popular freshwater fish such as catfish and carp.
with Atlas of Living Australia, , After its release in non-native North American waters, either accidentally or intentionally, the aggressive and predator-free snakehead's reputation as a "Frankenfish" or "monster fish" has become part of the culture Besides mentions on TV shows such as The Sopranos and The Office and CSI:NY episode "Sangre por Sangre" and Central Park episode "A Fish Called Snakehead", the snakehead has been featured in three Sci-fi Channel original pictures entitled Snakehead Terror, Frankenfish, and Swarm of the Snakehead. This air-breathing trick has enabled one species, the northern snakehead, to spread far and become an invasive nuisance in North America and elsewhere.
These unique traits include a shortened swim bladder and fewer vertebrae with ribs, features that show the dragon snakeheads are less specialized than regular snakeheads. These elongated, predatory fish are distinguished by their long dorsal fins, large mouths, and shiny teeth. resources, Indigenous Commons Attribution 3.0 Australia License. us, Education Snakeheads are valuable food fish. , According to the International Game Fish Association, Caleb Newton, a Spotsylvania County, Virginia, resident, caught a world-record 17 lb 6 oz (7.9 kg) northern snakehead at the junction of Aquia Creek and the Potomac River, United States, on June 1, 2013.
This has lowered the water table and could imperil some of the newfound obscure species that live there.  By 17 Mya, during the Early Miocene, Channidae had spread into western and central Eurasia, and by 8 Mya, during the late Tortonian, they existed throughout Africa and East Asia. Froese, Rainer and Pauly, Daniel, eds.
Each spawning-age female can release up to 15,000 eggs at once. Dragon snakeheads also have eyes and a reddish brown pigmentation—traits uncommon in subterranean fish, many of which are white and eyeless. datasets have provided data to the Atlas of Living Australia for this family. tools, Creative researchers, ALA for government and land | National Geographic - YouTube
His genetic analysis shows they may have diverged from their nearest relatives, snakeheads in the family Channidae, before Africa and India separated and spread apart 120 million years ago, Britz says. In parts of Asia and Africa, the snakehead is considered a valuable food fish, and is produced in aquacultures (fisheries motivation) or by accidental release (as was the case in Crofton, Maryland).
Larger species, such as C. striata, C. maculata, and Parachanna obscura, are farmed in aquaculture. We Snakeheads are thrust-feeders that consume plankton, aquatic insects, and mollusks when small. (Related: World’s largest cavefish discovered in India.). Humans have been introducing snakeheads to nonindigenous waters for over 100 years.
They have suprabranchial organs, which are primitive forms of labyrinth organs, that develop when they grow older. There are more than 50 species of Channidae snakeheads, which live in streams and lakes throughout Asia and Africa. Like us on Facebook to see similar stories, What is an exit poll? Studies of the fish’s anatomy help show that this species (and its sister species) belong to a previously unknown taxonomic family, Aenigmachannidae.

In the Animal Planet TV series River Monsters, Jeremy Wade shows a dramatization of a snakehead, "the fish from hell", stalking an unsuspecting baby and Chihuahua. Watching them can be mesmerizing, Britz says—they move “like a veil in the wind.”.
They are valuable as a food source and have become notorious as an intentionally released invasive species.
"History of introduction in the United States: Four species of snakeheads (Channa argus, C. marulius, C. micropeltes, and C. striata) have been recorded from open waters of the United States (California, Florida, Hawaii, Maine, Maryland, Massachusetts, and Rhode Island), and two have become established as reproducing populations.".
The Channidae are well represented in the fossil record and known from numerous specimens. These strange, long-bodied fish, which dwell in aquifers of porous rock, are rarely seen, only coming to the surface after flooding from heavy rains. a sighting, Discover
, 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. Britz says it’s unclear why the species have these traits, but suggests it may be because they are not exclusively subterranean.

These species are listed as ‘noxious’ under schedule 5 of the Fish Resources Management Regulations 1995. Britz travelled to India after Raghavan and other colleagues had collected more specimens, to scientifically describe the fish.
