The northern snakehead is a species of snakehead fish native to temperate East Asia, in China, Russia, North Korea, and South Korea. Their natural range goes from the Amur River watershed in Siberia and Manchuria down to Hainan. It is an important food fish and one of the most cultivated in its native region, with an estimated 500 tons produced every year in China and Korea alone. Due to this, the northern snakehead has been exported throughout the world and has managed to establish non-native populations in Central Asia and North America.
Channa is a genus of predatory fish in the family Channidae, commonly known as snakeheads, native to freshwater habitats in Asia. This genus contains about 50 scientifically described species. The genus has a wide natural distribution extending from Iraq in the west, to Indonesia and China in the east, and parts of Siberia in the Far East. A particularly high richness of species exists in Myanmar (Burma) and northeastern India, and many Channa species live nowhere else. In contrast, a few widespread species have been introduced to several regions outside their natural range, where they often become invasive. The large and medium-sized Channa species are among the most common staple food fish in several Asian countries, and they are extensively cultured. Apart from their importance as a food fish, snakeheads are consumed in some regions as a traditional medicine for wound healing and reducing postoperative pain and discomfort, and collected for the international aquarium pet trade.
The Alaotra grebe, also known as Delacour's little grebe or rusty grebe, is a recently extinct grebe that was endemic to Lake Alaotra and its surrounding lakes in Madagascar. Experts say that the grebe became extinct after carnivorous fish were introduced into its native habitat.
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 are primitive forms of labyrinth organs, that develop when they grow older. The two extant genera are Channa in Asia and Parachanna in Africa, consisting of more than 50 species.
The Borna snakehead, or Chel snakehead, Channa amphibeus, is an extremely rare species of snakehead. C. amphibeus is native only to the Chel River, of the Bhutan foothills, in northern Bengal, India.
The Barca snakehead is a rare species of snakehead. It is endemic to the upper Brahmaputra river basin in northeastern India and Bangladesh. Records from Nepal are of doubtful validity. Overall it has been assessed as data deficient by the IUCN, and in 2014 it was assessed as critically endangered in Bangladesh by the IUCN. In Assam, it is locally known as cheng garaka or garaka cheng.
Channa bleheri is a species of dwarf snakehead that is endemic to the Brahmaputra River basin in the Indian states of Assam and Arunachal Pradesh. It is among the most colorful species of snakehead.

Channa gachua, the dwarf snakehead, is a species of fish in the family Channidae. The name "dwarf snakehead" is also used for several other species of small snakeheads. C. gachua is native to freshwater habitats in southern Asia, where it has a wide distribution from Iran to Indonesia. This fish is considered to be a species complex, a group of several closely related taxa with one name. It is likely at least three to four different species, and further research may differentiate them. A few species such as Channa harcourtbutleri have been separated from the complex in recent decades. The easternmost population of C. gachua is often recognized as a separate species C. limbata, while the isolated Sri Lankan population often is recognized as C. kelaartii.
Channa striata, the striped snakehead, is a species of snakehead fish. It is also known as the common snakehead, chevron snakehead, or snakehead murrel and generally referred simply as mudfish.

Males have taller dorsal fins with more intense coloration, and narrower heads. It is endemic to Brahmaputra River basin. Its type locality is Dibrugarh, the most northeastern area of Assam, India. Dibrughar is the same type locality as that of Channa bleheri.
Channa burmanica is a species of snakehead which is endemic to northern Burma. It is a very small species of snakehead included in the informal group of dwarf snakeheads. Its colouring closely resembles that of Channa gachua and Channa bleheri. It is very rarely found in pet shops. It is also considered to be a mouthbrooder species, though no successful breeding has yet occurred.
Channa harcourtbutleri, the Burmese snakehead, is a species of snakehead endemic to Inle Lake and surroundings in Myanmar. Locally called nga ohn-ma, among aquarists it is considered one of the dwarf snakeheads, but no significant import for aquarists is known. It is one of the smaller species of snakehead and has a standard length of up to 19.4 cm (7.6 in). The specific name honors Sir Harcourt Butler, a British governor in the region.
Channa micropeltes, giant snakehead, giant mudfish or toman harimau, is among the largest species in the family Channidae, capable of growing to 1.5 m (4.9 ft) in length and a weight of 20 kg (44 lb).
